cut command wont work in shell??
--------------------------------------------------------------------------------
hi,
on linux command promt cut command work.
but the same command gives empty output in linus shell?
please help
F1=$(echo $line | cut -s -f26) NOT working in shell
cat file | cut -s -f26 work!
Since there is no such thing as the "linus shell", you will have to explain what you are actually referring to.
The command line IS the bash shell; when you refer to the "linux command prompt" you are really talking about the bash shell. It is unlikely that there is any other shell on your system, so saying something "works from the command prompt" but "not from the shell" does not make any sense: they are the same thing. It would be like if you had a red car parked outside and someone said "the bag is in your car, but not in the red car parked outside".

You'll have to try this in steps. When you are debugging a Bash script, it is helpful to echo the variables prior to the command that is failing. Most likely your variable doesn't have what you think it has.
Also, it would be very helpful to know what line has and what you are attempting to do with cut.
If this is a shell script, post some context.
