Return code for parallel running threads

Hi,

How to use the return code, for parallel running threads.

Ex-

grep pattern1 file1 file2 file3 file4 &
grep pattern1 file5 file6 file7 file8 &
grep pattern1 file9 file10 file11 file12 &

return_code=$?
if (return_code -eq 0)
then
echo "pattern found"
else
echo "pattern not found"
fi

Here, in this above samples of code, how to use return codes effectively, for the concurrent running greps, so that, i can get correct result for, "pattern1" is found in which grep.

It seems that, I need to use the thread locking and unlocking principle here. However, i am a bit confused, how to use this concept over here.

Please help.

Please indicate, if you need any further clarification of the problem.

Thanks and Regards,

Jitendriya Dash.

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) AUTHOR
