Replace characters in a string using their ascii value
Hi All,
In the HP Unix that i'm using when i initialise a string as Stalled="'30¬G'"
Stalled=$Stalled" '30¬C'", it is taking the character ¬ as a comma. I need to grep for 30¬G 30¬C in a file and take its count. But since this character ¬ is not being understood, the count returns a zero.
The ascii value of the character ¬ is 188.
I thought of replacing all occurrences of comma using something like
chr(188). But i dont know how to.
Could some one help me or give me some other idea to go about this. I need to do this urgently :-(
Thanks in advance...

ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci-
fied, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and
fed to grep.
If zgrep is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, zgrep uses
it as the grep program to be invoked. For example:
for sh: GREP=fgrep zgrep string files
for csh: (setenv GREP fgrep; zgrep string files)
