Full Discussion: Shell script to parse apache httpd line
Top Forums UNIX for Advanced & Expert Users Shell script to parse apache httpd line Post 302499498 by ctsgnb on Thursday 24th of February 2011 01:19:21 PM

Try this :

Code:
ps -ef | grep [h]ttpd | sed 's:^[^/]*::;s: .*::'

or
Code:
ps -ef | sed '/[h]ttpd/!d;s:^[^/]*::;s: .*::'


Note :
[h]ttpdi instead of just httpd is a tip to avoid the "grep -v grep"
You also can speed up the process by displaying the first occurrence you will find and then quit the sed loop (by adding a ;q at the end of the sed command), so that if you have multiple httpd deamon, it will only display the first occurrence found.

Code:
ps -ef | grep [h]ttpd | sed 's:^[^/]*::;s: .*::;q'

If you have more than 1 apache so several httpd running at different location you might use the command without the ;q and add a | uniq

Even better, you can even save the grep pipe with :

Code:
ps -ef | sed '/[h]ttpd/!d;s:^[^/]*::;s: .*::;q'

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.
