How to get the for loop output from a remote server in UNIX shell scripting?
Hi,

I am using ksh , when i try to use for loop i am getting the expected output.

Code:
$for variable in $(ps -fu user | grep -i something/ | grep -i something | grep -v grep | awk '{print $2}');do
> grep $variable /tmp/some_path/*/*
> done

when tried the below to remote server, getting the entire content rather than the expected output.

Code:
$for variable in $(ssh server_name "ps -fu user | grep -i something/ | grep -i something | grep -v grep | awk '{print $2}'");do
> grep $variable /tmp/some_path/*/*
> done

I tried the below to remote server , but getting the below error.

Code:
$ssh server_name "for variable in $(ps -fu user | grep -i something/ | grep -i something | grep -v grep | awk '{print $2}');do
> grep $variable /tmp/some_path/*/*;
> done"

Code:
/bin/ksh: syntax error at line 2: `31656' unexpected

I am not sure what is the syntax mistake i did in the above script.

Please advise.

Thanks,
Regards,
karthikram

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  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.
