suppose your string is stored in a variable str1, the awk syntax is<br />
<br />
substr(str1, 4),<br />
for unknown length, example<br />
<br />
echo 1234567890 | awk {'print substr($0, 4)'}<br />

Yes, but how do you assign the result to another variable?<br />
<br />
For example,<br />
if $NUM is an argument passed to a script,<br />
could this be done:<br />
$short=`echo $NUM | awk '{print substr($NUM,4}'`<br />
<br />
I think I'm doing something wrong because the script fails<br />
to output the value of $short<br />
<br />

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
