temp_22
temp_33
temp_123

ls -1 | sort -t '_' -k 2,2n

or

ls -1 | sort -n -t '_' +1

-anchal

printf "%s\n" temp_*|sort -t_ -k2n

actually i have the files having names

ABC.tl_temp_52
TCE.tl_temp_53

and so on......i.e there are two underscore..

so the command fails there ...

it works fine with 1 underscore...

If you have zsh:

set -- temp_*;print -l ${(on)@}

Otherwise:

printf "%s\n" ABC.tl_temp_*|sort -t_ -k3n

Thanks buddy ,now that works fine....
I'll have to check how this command works ....
If u have time can u explani..

in that case the numeric part is now 3rd field ( with _ as a delim )
so use
ls -1 | sort -t '_' -k 3,3n

or

ls -1 | sort -n -t '_' +2
