Swiss File Knife 1.9.8 Extended Edition
- Read .zip, .tar.gz and .tar.bz2 contents on the command line,
including archive files nested within other archives,
with these commands:
sfk list, lindex, (x)find, (x)hexfind, filter, snapto, md5gento, filefind.
The following restrictions apply:
- archive file contents must fit completely into memory.
in general, archives below 100 mb should be ok,
but beyond that your machine must provide enough memory.
zip files must use a normal compression format (DEFLATE),
e.g. as it is produced by the InfoZIP or WinZIP tool.
(most zip files in the internet use DEFLATE compression.)
exotic compressions and 64-bit zip files are NOT supported.
.tar, .tar.gz and .tar.bz2 files produced by non-Windows/Linux
operating systems, or produced by old and exotic tar tools
may slightly differ in their format, and may fail to read.
sfk ofind -arc is not possible.
you can use xfind -arc also to search office contents,
which will however display raw xml data.
(demo available in sfk base)
To make sure than you can load the archive files you're
most interested in, test loading first in SFK Base (using the XE Demo mode).
To browse and search .zip, .tar.gz and .tar.bz2 text contents
interactively at high speed,
take a look at
Depeche View Professional.
Replace strings or byte sequences in text and binary files at high speed,
with optional file-to-file replace or use of temporary files,
supporting large files not limited
by the amount of available memory.
Execution times are heavily dependent on content,
search patterns, and hardware.
1 GB file (1000000000 bytes) with binary random data created by
sfk make-random-file test.dat 1g
replace every zero byte by two bytes 0x0102 with command
sfk replace test.dat -bin /00/0102/ -usetmp
done in 25 seconds on a Core i3 CPU with 2.13 GHz.
But in general, replacing
within a gigabyte file is a matter of minutes, not hours.
Note: temporary files are not active by default.
To enable them if output exceeds 300 MB,
or the environment variable
Search and Replace using wildcards and SFK Expressions.
SFK Expressions are not "regular expressions",
but rather simple search patterns
allowing to search for character classes like [chars of a-z0-9] or [bytes not \x00].
They are of limited flexibility, but easy to write and understand.
Learn more by downloading the free SFK Base,
then type sfk xfind to search
through text files using SFK Expressions. SFK Base provides read-only commands
for wildcard search. SFK XE also allows to reformat and rewrite the found data
by command xreplace, in multiple files, and in large files not limited
by the memory.
