To cut end string from line

visu · #1 (**permalink**) 12-19-2007

HI,

I want to cut end string from line.

e.g. i have following input line

/users/home/test.txt

I want to get end string 'test.txt' from above line and length of that end string will change and it always start after '/'.

Thanks,

Visu

Of course!

if you're writing shell scripts for system stuff or if you are working as root, bourne is the only safe shell to use IMO.
For simple userland stuff I'll use bash, but even then I still script in sh - the extra features of ksh are nice but I only use ksh script when I need them as sh scripts work in everything else.
