wow..!! , i did not know that shell has the ability to treat first one as variable assignment and next one it expands into a command. Thats a new thing i learnt today. Thank you
Both are variable assignments, but since they are at the beginning of a command (not complete commands on their own), the settings only affect affect the environment of the command being run. They do not affect the current shell execution environment. For example:
Hi All,
I need to pass param on aix "errpt -a -s MMDDHHMMYY -e MMDDHHMMYY".
How do I read the date+time on the system and pass it as parameter? I need also the -s as previous day and the -e as current day.
Thanks,
