Hello again,
I was thinking since we were already talking about "if" how would i go about setting up an if statement with free that would allow me to do an if statement based off how much free memory is remaining.
something like
"
free > Memory.txt
if (FeeMem <= 1000)
then
ps > psinfo.txt
else
rm Memory.txt
exit
"
but i do not want to have to save "free" output into a file just to find the free memory information on it to place it into my "if" statement. Everything must be done without pipes.
any advice would be grateful.
Thank you

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 invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, 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 the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
