how to get one character - Shell Programming and Scripting

woosaah · #1 01-30-2006

I just need to know how to get one character in a string

i tried

Code:

if [[ $# -eq 1 ]] && [[ cut -b54 $1 -ne 'X' ]]

but that didnt seam to work keep coming up that -b5 was unexpected.

i am not sure if the cut command is a good way of doing this.

i am still trying to figure it out. any help would be good

cheers

Almost there.... you need backticks

Code:

if [[ $# -eq 1 ]] && [[ `cut -b54 $1` -ne 'X' ]]

cheers zazzybob, now it just seams to come up with the error

Code:

iip[44]: cut -b54 $1: bad number

i have tried varing the number but that doesnt seam to be a problem if i use it on command line it works no problem. is it because its in an if statement (which i doubt)

eh i not sure

ksh for anyone that needs to know

Ahh... ksh - you'll need

`cut...` != 'X'

cheers
