Top Forums Shell Programming and Scripting Bash: How to remove the last character of a string? Post 302599679 by mikelking on Friday 17th of February 2012 10:37:39 PM

There's a nice trimString() function in blib (the bash library link-> //bit.ly/i7tZWH) that does this. Of course it's still under development so your mileage may vary.

Essentially you can use something like... ${1:0:$((${#1}-1))}.

Note the subshell call may no be necessary...

Cheers,
Mikel King
