AROS i386 build of gsar, originally found on aminet. Compiled by P. Besser
please read the full readme files and documentation provided in the

gsar (General Search And Replace) is a utility for searching for and
--- optionally --- replacing strings in both text and binary files.
The search and replace strings can contain all kinds of characters
(0--255), i.e. Ctrl characters and extended ASCII as well. 

The algorithm used is a variation of the Boyer-Moore search algorithm,
modified to search binary files. As a result of this, gsar is blindingly

Opposed to line oriented search programs (like grep(1)), gsar will find
all matches on a line. Actually, gsar doesn't know anything about lines
at all, all files and strings are treated as binary. 

Gsar can search one or several files for a string and report the
occurrences. Gsar can read one file, search for a string, replace
it with some other string, and create a new file containing the changes.
Gsar can perform a search and replace in multiple files, overwriting the
originals. Finally, gsar can work as a filter, reading from standard
input and writing to standard output.


- replace string FORM with TEST in file image.iff
gsar -o -sFORM -rTEST image.iff

- display search and replace strings only
gsar -B -sFORM -rTEST image.iff

- display ascii search result only
gsar -sFORM -c16 image.iff

- display hex search result only
gsar -sFORM -x16 image.iff
