i have a set of commands to be executed, which is working perfectly when executed from terminal but when its put in a shell script its not working. how do i resolve it

are the commands in script present in system path ?
what error do you get ?

Im getting file not found exception, even though it works perfectly when i execute line by line from terminal.

have you exported the the location of the file for which you are getting the error in $PATH ?

i havenot exported any specific files. But it works well when i execute the commands line by line from terminal
