Hi,

Thanks for you help, but I have errors when I execute the command:

Code:

root@local:~# find /var/cache/nginx/portal -maxdepth 1 -type d | xargs -P 16 -n 1 head -2 | grep -Rl "topic" | sort -u
head: error reading `/var/cache/nginx/portal': Is a directory
head: error reading `/var/cache/nginx/portal/1': Is a directory
head: error reading `/var/cache/nginx/portal/a': Is a directory
head: error reading `/var/cache/nginx/portal/4': Is a directory
head: head: error reading `/var/cache/nginx/portal/c': Is a directory

Without head I get:

Code:

root@local:~# find /var/cache/nginx/portal -maxdepth 1 -type d | xargs -P 16 -n 1 grep -Rl "topic" | sort -u
/var/cache/nginx/portal/8/d2/c7271e2a8985029a4194f1a43c256d28

...... etc

The full command can be changed if it's easy to archive the same results.

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)
