zapigrep.cmd (ye olde REXX procedure for OS/2)
|
||
|
|
|
||
|
|
Script to search members of a zipfile for a string and print the names of
|
||
|
|
any such members (and, optionally, the matching text).
|
||
|
|
|
||
|
|
This is the zipgrep.cmd program completely rewritten to take advantage
|
||
|
|
of the REXX API. Among the improvements are:
|
||
|
|
egrep no longer needed. All work done by API and this script.
|
||
|
|
Added option switches.
|
||
|
|
|
||
|
|
Be aware, however, that this script does not support regular expressions
|
||
|
|
as zipgrep does.
