sfk filter [fileOrDir] -selectoption(s) -processoption(s) sfk filt -selectoption(s) -processoption(s) -dir mydir -file .ext1 .ext2 sfk filter [-memlimit=n] -write inoutfile -replacepattern(s) filter and change text lines, from standard input, or from file(s). input lines may have a maximum length of 4000 characters. line selection options -+pat1 -+pat2 [...] - include lines containing pat1 OR pat2 ++pat1 ++pat2 [...] - include lines containing pat1 AND pat2 -ls+pat1 - include lines starting with pat1 -le+pat1 -le+pat2 - include lines ending with pat1 OR pat2 -!pat1 -!pat2 - exclude lines containing pat1 OR pat2 -ls!pat1 - exclude lines starting with pat1 -le!pat1 -le!pat2 - exclude lines ending with pat1 or pat2 -no-empty-lines - exclude empty lines -no-blank-lines - exclude lines containing just whitespaces -inc[lude] p1 to p2 - include only lines within blocks surrounded by boundary lines containing patterns p1 or p2 -inc- p1 to p2 - same, but exclude boundary lines on output -cut[-] p1 to p2 - remove block of lines from p1 until p2 -inc[-] "*" to p1 - include all from text start until marker -cut[-] p1 to "*" - cut all from marker line until end of text -nocheck - with inc, cut: ignore block endings without a start -addmark txt - with inc, cut: insert txt after every processed block -context=n - select n lines of context around hit lines -precon=5:blue - select context before or after hit lines, -postcon=5:cyan:--- in blue or cyan, with separator "---". -unique [-case] - if same line occurs twice, keep only first. default is case insensitive text comparison. -global-unique - when filtering multiple files in one command, then -unique applies to lines in the same file, and -global-unique applies across all files. this will cache the text of all files in memory and may not be used with very large files. -keep pattern - after -unique: make an exception for lines containing the given pattern, and keep them even if redundant. -keep-empty, -keep-blank - always keep empty or whitespace lines. text processing options applied after line selection options only. -rep[lace] _src_dest_ replace string src by dest. first character is separator character (e.g. _). src is case-insensitive. to select case-sensitive search, say -case. -lsrep[lace], -lerep[lace] same as -replace, but replaces only once at line start or line end. -high[light] color pattern : highlight matching parts within lines. color : red = dark red, Red = bright red, green, blue, yellow, cyan, magenta, default. pattern : e.g. "GET * HTTP/" type "sfk help colors" for more about colors. -lshigh[light], -lehigh[light] same as -highlight, but only at line start or line end. -sep[arate] "; " -form "$col1 mytext $[-0n.nq]col2 ..." break every line into columns separated by any character listed after -sep, then reformat the text according to a user-defined mask similar to printf. when leaving out -sep, the whole line is packed into column 1. if -spat was specified, then -form also supports slash patterns like \t. google for "printf syntax" to get more details. example: -form "$40col1 $-3.5col2 $05qline $(10.10qcount+1000)" reformat column 1 as right-ordered with at least 40 chars, column 2 left- ordered with at least 3 and a maximum of 5 chars, then add the input line number, "q"uoted, right justified with 5 digits, prefixed by zeros, then the output line number plus 1000 within quotes. NOTE: some examples may not work in an sfk script, see section "common errors" below. adding values so far only works with (q)line and (q)count. -tabform "$col1 mytext ..." split and reformat columns of tab separated csv data. -uform "#40col1 #-3.5col2 #05qline" the same as -form but using unix style syntax. short for filter -upat. -blocksep " " = treat blocks of whitespace as single whitespace separator. -join[lines] join output lines, do not print linefeeds. -wrap[=n] wrap output lines near console width [or at column n]. set SFK_CONFIG=columns:n to define or override the console width. conditional text processing -[ls/le]where pattern -replace | -highlight | -sep ... -form replace, highlight or reformat lines matching the given pattern. all lines that do not match the pattern stay unchanged. -within pattern -replace _from_to_ replace text in a part of the line matching the given pattern. the rest of the line text stays unchanged. pattern support wildcards * and ? are active by default. add -lit[eral] to disable. slash patterns are NOT active by default. add -spat to use \t \q etc. if you need the wildcard * but ALSO want to find/replace '*' characters: add -spat, then specify \* or \? to find/replace '*' or '?' characters. instead of typing "sfk filter -spat -rep" all the time, you may use the short form "sfk filt -srep". the same applies for -(s)sep, -(s)form etc. unified syntax since sfk 1.5.4 you can also use -: -ls: -le: under windows. filter ... -uform or filter -upat ... -form uses # instead of $. further options -verbose show names of all files which are currently scanned. -write do not print output to console but overwrite input file(s). only files with actual text changes will be rewritten. this function may be used only with plain ASCII files, not with binaries like .doc, .xls. see also "sfk replace". -write -to msk do not overwrite input files, but save according to mask msk, e.g. tmp\$file . saves only changed files. say -writeall to write all files, including those without changes. -memlimit=mb when using -write, output is cached in memory, which is limited to 300 mb. use this option to extend, e.g. -memlimit=400 -yes -write simulates by default. add -yes to really write changes. -snap detect snapfiles and list subfile names having text matches. -snapwithnames same as -snap, but include subfile names in filtering. -nofile[names] do not list filenames, do not indent text lines. -count, -cnt preceed all result lines by output line counter -lnum preceed all result lines by input line number -case compare case-sensitive (not default) -lit[eral] treat wildcards * and ? as normal chars (read more above). -hidden include hidden and system files. -noinfo do not warn on line selection combined with -write. -noop \" no operation, take the \" parameter but do nothing. may help if your (windows) shell miscounts quotations. -hitfiles if another command follows (e.g. +run or +ffilter), pass a list of files containing at least one hit. -nocconv disable umlaut and accent character conversions during output to console. "sfk help opt" for details. -justrc print no output, just set return code on matching lines. list of possible input sources from stdin : type x.txt | sfk filter -+pattern from single input file : sfk filter x.txt -+pattern text from chained command : sfk list mydir .txt +filter -+pattern from many files, directly : sfk filter -+pattern -dir mydir -file .txt from many files, by chain : sfk list mydir .txt +filefilter -+pattern in general, whenever you need to make sure that file contents (not the file names) are processed, prefer to say "filefilter" or "ffilt". return codes for batch files 0 normal execution, no matching lines found. 1 normal execution, matching lines found. with -write: returns rc 1 only if any changes were written. >1 major error occurred. see "sfk help opt" for error handling options. common errors when using filter -form within sfk scripts, expressions like $10.10col1 may collide with script parameters $1 $2 $3. to solve this, use brackets like $(10.10col1), or "sfk label ... -prefix=%", or -uform. see also sfk find find words in text and binary files. faster, but less flexible. sfk hexfind find text or binary data in binary files, with hex dump output. sfk replace replaces many strings in parallel, in text and binary files. sfk help color for the list of color names. sfk view a high speed GUI text filter tool. filters text lines instantly as you type, with a simple syntax like "foo AND htm NOT html". beware of Shell Command Characters. to find or replace text containing characters < > | ! & you must add quotes "" around parameters, or the shell will destroy your command. it splits the command into parts, and gives SFK only the first part, producing unreadable errors. therefore -replace _<br>_ _ must be written like: -replace "_<br>_ _" examples anyprog | sfk filter -+error: -!warning run command anyprog, filter output for error messages, remove warning messages. sfk filter result.txt -rep "_\_/_" -rep "xC:/xD:/x" read result.txt, turn all \ slashes into /, and C:/ expressions to D:/ the quotes "" are optional here, and just added for safety. sfk filter index.html -rep "_<u>_<b>_" -rep "_</u>_</b>_" -write replace underlining by bold in an HTML text. quotes "" are strictly required here, otherwise the shell environment would split the command at the < and > characters. add option -yes to really rewrite the file. sfk filter export.csv -sep ";" -format "title: $-40col2 remark: $-60col5" reformat comma-separated data, exported from spreadsheet, as ascii text. sfk stat . +filter -blocksep " " -format "$4col1 mb in folder: $col5" reformats output of the stat command. sfk filter mycsv.txt >out.txt -spat -rep _\"__ -rep _\t__ -rep "_;_\"\t\"_" -form "$qcol1" read semicolon-separated spreadsheet data mycsv, strip all double colons and tab characters from data fields. replace field separator ";" by TAB, and surround all fields by double colon. -form without -sep means "pack the whole line into $col1", allowing -form to add quotes at start and end of each line. sfk filter logs\access.log "-+GET * 404" list all lines from access.log containing a phrase with GET and 404. sfk filter log.txt "-ls!??.??.???? ??:??:?? * *" excludes lines from log.txt starting with a date, and having two more words, like "20.05.2007 07:23:09 org.whatever.server main" cd | sfk run -idirs "sfk filt tpl.conf >httpd.conf -rep _AbsWorkDir_$path_" create httpd.conf from tpl.conf, replacing the word "AbsWorkDir" by the path from which the command is run. note we can NOT use -spat in this case, otherwise a pathname like C:\temp would produce garbage (contains slash pattern "\t"). sfk filter in.txt -spat -sep "\t" -rep _\q__ -form "INSERT INTO MYDOCS (DOC_ID, DESCRIPTION) VALUES ('TestDoc$03line','$col2');" this example (typed in one line) creates a list of SQL statements, using tab- separated, quoted input data, and using the input line number for document ids. the -rep _\q__ means the same as -rep _\"__ - it strips quotes from the input, but using \q is safer then \" as it doesn't let the shell miscount quotes. sfk list documents .txt +filter -+big*foo -+wide*foo from all .txt files in documents, filter the filenames (NOT the file contents) for big*foo OR wide*foo. sfk list documents .txt +filefilter -+big*foo -+wide*foo from all .txt files in documents, filter the file contents (NOT the names) for text lines containing big*foo OR wide*foo. sfk list logfiles .txt +filefilter -global-unique +tofile mixedlog.txt join all .txt files from logfiles into one output file mixedlog.txt, dropping all redundant text lines. works only if logfile records are prefixed by a unique record ID, and if overall text data is less than available memory, because all data is cached during processing. sfk list logfiles .txt +ffilter -global-unique -write -to mytmp\$file sfk snapto=mixedlog.txt mytmp same as above in two commands, using temporary files to allow more data. bin\runserver.bat 2>&1 | sfk filter -+exception filter standard output AND error stream ("2>") for exceptions sfk filter result.txt -+error -justrc IF %ERRORLEVEL%==1 GOTO foundError in a batchfile: jump to label foundError if text "error" was found within file result.txt. with -justrc no output is printed to terminal. sfk filt log.txt -high cyan "*.*.*(*.java:*)" -high green "sql select *" dump log.txt, listing java stack traces in cyan, and sql selects in green. sfk filt x.html -where "000099" -rep "_<font*000099*>_<b>_" -rep "_</font>_</b>_" replaces html <font> commands by <b>, but only in lines with "000099" (=blue). sfk filt foo.cpp -cut "ifdef barmode" to "endif // barmode" strip blocks of lines from foo.cpp, surrounded by the given patterns. sfk filt csv.txt -spat -within "\q*\q" -rep _,_\x01_ -rep _,_\t_ -rep _\x01_,_ change separators in comma separated data from comma to tab, also taking care of quotes, by replacing in-quote commas by a placeholder (\x01). if the data contains escaped quotes like "" then further prefiltering can be necessary, like removing those quotes by -sreplace _\q\q__ sfk filt mysrc.cpp "-+fopen(" -postcontext=3:blue:----- +view filter source file "mysrc.cpp" for fopen calls, and list the following three lines (post context) of every call, separating outputs by ----- and showing the whole result in Depeche View ("sfk view" for more). see also: sfk replace - find and replace text of equal length. works also with binary files, and allows, for example, to replace (CR)LF line endings completely by a different string. sfk find - find text in text and binary files.
