LOG=/etc/security/aixpert/log/aixpert.log
exec 1>>$LOG
exec 2>&1
I know that we are logging into a file… but what exactly it does? especially the 1, 2, >& and in general
execmanipulates file descriptors. In particular, you redirect file descriptor 1 (which corresponds to C’sstdout) to the designated file on disk, and you redirect file descriptor 2 (stderr) to file descriptor 1.So everything ends up getting written into the log file rather than being printed on the console.
