sfk replace singleFile [-text] /src/dst/ [pattern2] [...] [-yes]
sfk replace -[s]pat -bin[ary] /A0A1A2/B5B6B7/ -dir anydir -file .ext1 [-yes]
sfk rep [-dump [-wide]] -bylist words.txt file1 [file2 ...] [-yes]
replace text or binary data in text and binary files.
may replace many different patterns in parallel.
Multiple search patterns are executed in the given sequence. Mind this
if they overlap, e.g. /foo/bar/ /foosys/thesys/ makes no sense (foo is
replaced by the first expression, so the 2nd one will fail to match).
by default, replace functions run in SIMULATION mode,
previewing hits without changing anything. add -yes to apply changes.
Changing binaries may lead to unpredictable results, therefore keep
backups of your files in any case.
license notice
this is the open source version of sfk replace.
replacing source / target patterns of different length is slower
and may require much memory compared to replacements of same length.
SFK Plus or XE contain a different implementation with high performance.
subdirectories are included by default
the sfk default for most commands is to process the given directories,
as well as all subdirs within them. specify -nosub to disable this.
options
-nosub do not include files in subdirectories.
-nobin[ary] skip binary files.
-case case-sensitive text comparison. default is case-insensitive
comparison for all -text strings, but NOT for -bin blocks.
case-sensitive comparison is faster then case-insensitive.
for further details type: sfk help nocase
-nocase force case-insensitive comparison ALSO on -bin patterns.
-pat starts a list of search or replace patterns of the form
xsrcxdstx where x is the separator char, src the source
to search for, and dst the destination to replace it with.
e.g. /foo/bar/ or _foo_bar_ both replace foo by bar.
-pat is not required if a single filename is given.
-text the same as -pat, starting a text pattern list.
-spat same as -pat but also activates slash patterns like \t .
type "sfk help pat" for the list of possible patterns.
-spats[trict] same as -spat, but stops with error on undefined
slash patterns like \m in C:\myproj. every slash
must then be escaped, e.g. using C:\\myproj.
-bin[ary] starts a list of binary replace patterns, specified
as hexcode like /0A0D/2020/
-bylist x.txt read search patterns from a file x.txt, supporting
multiple lines per pattern. (add -full for more.)
-bylinelist x read /from/to/ or just /from/ patterns from a file x
with one pattern per line. (add -full for more.)
-by(line)list does not support sfk variables.
to use variables in patterns create an sfk script
with patterns as parameters. "sfk script" for more.
-recsize with same length replacements: set input record size
for processing (default=100k)
-firsthit process only first found pattern match per file.
-maxscan=nm stop searching after (approximately) first n megabytes
per file. can be used only with same length replace.
-quiet do not show progress infos.
-stat show statistics like hits per pattern and no. of files.
-perf show performance statistics.
-memlimit=nm with different-length replacements, files must be loaded
into memory for processing. the default limit for memory
use is 300 MB. set -memlimit=500m to select 500 MB.
-full print full help text telling about -bylist pattern files,
special character case sensitivity and nested or repeated
replace behaviour.
output options
-dump create hexdump of search hits or replaced text.
-wide with -dump: show 16 bytes per line.
-lean with -dump: show 8 bytes per line.
-dumpfrom always dump search hits but not replaced text.
-dumpall dump search text and replaced text.
-nodump do not create a hexdump, list only matching files.
-astext no hexdump, but print search hits as plain text.
use this only with plain text files, not binary.
-showle highlight CR/LF line endings in hex dump output
-context=n with hexdump: show additional n bytes of context.
-reldist with hexdump: tell relative distances to previous hits.
-to dir\$file write output files to given path. for details about
output file masks, type "sfk help opt" or "sfk run".
-tofile x write output data to a single output filename x
(which is not interpreted as a mask but taken as is).
-more[n] pause output every 30 or n lines.
return codes for batch files
0 = no matches, 1 = matches found, >1 = major error occurred.
see also "sfk help opt" on how to influence error processing.
about nested replacement patterns
sfk replace myfile.dat /foo/bar/ /bar/goo/
with SFK base, "foo" will be replaced by "bar" and then
immediately "bar" is replaced again by "goo".
with SFK Plus or XE, a replaced part of text is not replaced
again in the same command, so "foo" stays replaced by "bar".
unexpected repeat replace behaviour
depending on the input data and search/replace expressions,
it can happen that running the same replace multiple times
on the same file produces further hits that didn't exist
in the first run. add option -full to read more on this.
quoted multi line parameters are supported in scripts
using full trim. type "sfk script" for details.
performance notice
the system may cache output file(s), writing to disk in
background after sfk has finished. subsequent batch file
commands may execute slower.
office file support
sfk ofind search in .xml text file contents of
office files like .docx .xlsx .ods .odt.

beware of Shell Command Characters.
to find or replace text patterns containing spaces or special
characters like <>|!&?* you must add quotes "" around parameters
or the shell environment will destroy your command. for example,
pattern /foo bar/other/ must be written like "/foo bar/other/"
within a .bat or .cmd file the percent % must be escaped like %%
even within quotes: sfk echo -spat "percent %% is a percent \x25"

common usage errors
sfk hexfind in.txt "/foo\r\n/"
will not find "foo" at line ends, but searches literal
strings like "slash and r". add option -spat to enable
slash patterns, converting \r\n to real CRLF codes,
or use xhexfind where slash patterns are default.
sfk hexfind mydir "/foo*bar/"
will not find "foo" and "bar" with any characters
inbetween, but searches a literal star "*".
use xhexfind to enable search with wildcards.
sfk rep in.txt "/foo[0.1000 bytes]bar/---/"
will not replace up to 1000 bytes between "foo" and "bar",
but replaces a literal string "foo" then "[1000 bytes]"
then "bar". use xed or xreplace instead.
examples
sfk replace myfile.dat "/Lemon/Curry/"
replace Lemon by Curry within myfile.dat. search is
case-insensitive, therefore "lemon" will be replaced as well.
the quotes "" are optional here.
sfk replace -pat /FooCase// -dir . -file .txt
search for FooCase in all .txt files below current directory.
note that if you leave out the single fileOrDir parameter,
you have to say -[s]pat, -bin or -text first to tell clearly
that you will specify the target fileset later on.
sfk rep -spat "/The foo/The\tbar/" -dir mydocs
replaces "The foo" by "The" and "bar" separated by TAB char,
within all files within mydocs.
sfk rep -binary /1A/20/ -dir docs -file .txt .info .note
replaces all bytes with code 0x1A by code 0x20, in all .txt,
.info and .note files, in directory docs and all subdirectories.
sfk replace tmp\image.dat -bylist patches.txt
searches for source patterns in file tmp\image.dat,
replaces by patterns specified in patches.txt
SFK Base and XE: swap text in two steps
sfk -yes rep io.txt /foo34/foo99/ /foo12/foo34/ +rep /foo99/foo12/
replaces foo12 by foo34 and vice versa. with SFK Base, a word
which is replaced may be replaced again by a following pattern,
therefore the intermediate step: turn foo34 into something
not used anywhere in io.txt, then replace foo12, then replace
the intermediate pattern back in a second replace command
on the same file.
SFK XE only: swap text in one step
sfk rep io.txt /foo12/foo34/ /foo34/foo12/ -yes
replaces foo12 by foo34 and vice versa. with XE, a word which
is replaced is not looked at again in the same command, so
"foo34" from the first pattern is not changed by the 2nd.
sfk hexfind mydir -pat /FooCase/ +list -late
do not replace, just find binary files containing "FooCase",
then list them sorted by time. also accepts -bylist files.
sfk replace -binary /666f6f/626172/ -dir mydir -file .dat
replace binary data with hex values 0x66, 0x6f, 0x6f
by data with values 0x62, 0x61, 0x72 in all .dat files.
example with output:
preparing a replacement of pattern "class Foo".
sfk rep testfiles "/class foo/class Other/" -dump
output:
