Or similar to what you had already:
Like in elixir sinari's example, the -i switch is for "ignore case".
i was looking for something more complex. the "-i" will be slower when grepping through large files, which is what i'm dealing with.
i was thinking something along the lines of:
in this example, i know which letters may be small/upper case. so i took that into consideration. there are cases when u wont know, and i wanted to find a way to account for that, without using the "-i".

Hi
I have a such conditional:
SPAMH="it is SPAM"
if grep -q $SPAMH $NMDIR/$mail; then
SPAMHFLAG=1
else
SPAMHFLAG=0
fi
And grep doesn't catch this string, even it exists there. I think it's a problem with passing $SPAMH to grep. I tried... (2 Replies)

Hey Guys & Gals,
I am trying to figure out how one would go about printing all

Hi!
I was looking for files to clean out, and I remembered reading somewhere that you could pipe the output of grep to rm. But I prefer to mv stuff to ~/.Trash/
I thought I'd try something like this:
ls ~/Library/Preferences/ |grep '.*.\.iTunes\.plist\..*' |xargs -J % mv % ~/.Trash/
I... (12 Replies)

zgrep
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)
