I have a function inside a file. THe function name and filename is different. THis function works well, if I run it in the same shell. But if I put it in ascript and call ./function name, it says "Function name not found". I use "typeset -f" in the shell and it shows the function as one of the entries. But when I try to use the same "typeset -f" in he script, it does not show any function name. 1)Things I tried unsuccessfully to rectify the issue: 1)used "typeset -fx <function name>" 2) used "typeset -fx <Filename>" 3) Tried putting a FPATH variable pointing to the directory the function is present and then executing the command. 4) Using autoload command for both "filename and function name".

Put your function(s) into a separate shell script and source them. . ./my_functions.ksh

It works perfectly fine after I source the file as you said. The functions need not be put into a seperate shell script. The script which holds the function and also other commands could be sourced. Thank you very much.
