UNIX for Dummies Questions & Answers

hi
i wrote a script to run 'C' executable which will create a new file, after that util is completed, i have to change the file ownership to some other user. for that i used "chown" for changing the file permission in Korn script

but it is throwing error is "operation not permited" please suggest altrenate way to do this.

is it possible to use 'su' login in the script or else temporarily login with user and pass? how?

set

Code:

umask 000

in your script before you call the C executable.

still i am getting same error

umask 000
create_file ! C executable
chown ilayans $fil_name


error is chown: txt123.txt: Operation not permitted.
