Hey,

I am trying to remove the first and last character in a string. I want to do this as efficiently as possible so the it will execute quickly in my overall script. I am trying to use the substitute command, but can’t figure out the reg expression.

The following line will remove the first character.

substitute("^[(\.)]", $command, "");

This line will remove the last character in the string.

substitute("[(.)]*$" , $command,"");

How can I combine these two reg expressions so that it will remove the “.” character from the beginning and end of my string.

Thanks!

Wes

are you limited to using substitute for speed?
you could use:

substring $command 2 (`size($command)`-1);

I did a speed test and there was no real difference between substituting one character or using substring.
Speed test was over 1000 iterations.

No real reason for substitute. I’ll use substring instead. Thanks much for the help!
