Re: Unix script newbie

Hi Sonia,

U can use awk, there u have substr fucntion. Something simple like that:

ls -al BUSH_* | awk '{ print substr($9,x,y) "your_string" }' > urfile

you can make a file by puting cp or mv whatever u want as a string then execute urfile, don't forget to do chmod 755 urfile

See [$man awk] for other functions available in awk.

hth,
Jakh
