Hi, 
 
The &quot;^&quot; in the regular expression means beginning-of-the-line. As &quot;gcc.4.1.1.tar&quot; is not 
something usually typed at the beginning of a command, maybe there it is the mistake. 
 
Try then: 
 
for i in `cut -d: -f6 /etc/passwd` 
do 
&nbsp; &nbsp; &nbsp;if [ -f &quot;$i/.sh_history&quot; ] 
&nbsp; &nbsp; &nbsp;then 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; echo &quot;$i/.sh_history&quot; 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; grep &quot;gcc.4.1.1.tar&quot; &quot;$i/.sh_history&quot; 
&nbsp; &nbsp; &nbsp;fi 
done

Hi,

The "^" in the regular expression means beginning-of-the-line. As "gcc.4.1.1.tar" is not
something usually typed at the beginning of a command, maybe there it is the mistake.

Try then:

for i in `cut -d: -f6 /etc/passwd`
do
     if [ -f "$i/.sh_history" ]
     then
          echo "$i/.sh_history"
          grep "gcc.4.1.1.tar" "$i/.sh_history"
     fi
done

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
