If you are using gnu grep, use the -r switch to recursively search.<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;grep -r word /*<br />
<br />
Otherwise use find:<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;find / -type f | xargs grep word<br />
<br />
If you don't have xargs, use find -exec<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;find / -type f -exec grep word {} \;<br />
<br />
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />

How to find a word in all files under / ?

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.
