I need to use gzip and make the date (month and year) part of the output filename.
How can this be done.

example ;

input filename: FMMI.HHS.JJJJ
FMMI.HHS.JJJJ

output file name: FMMI.HHS.0112 (MMYY)

Very late to answer this, but…

One way to manipulate the date variable is:

DAY=$(date +”%d”)
DAY=$((DAY-1))
echo $DAY

No need to be rude. Each setup has unique requirements. So I used MM-DD-YYYY format, but that doesn’t mean I’m an idiot.

Have a nice day!

Exactly, what kind of idiot would use the MONTH-DAY-YEAR format for filenames? Once again the comment section has a higher quality than the article.

What about to start apps via script and set today’s date to log at the time of app start?

Okay, but how do I retrieve and format YESTERDAY’s date? Or, more generally, how do I perform date “arithmetic” from a shell script (adding days / weeks, etc)?

Take a look at log4sh [http://log4sh.sourceforge.net/] as well. It might be a better choice for your logging needs.

IMHU, to see a sorted list of log files the best date options is “+%Y%m%d%H%M%S”. Separate fields with hyphen could make it more human readable.

When a lot of instances of your program is running simultaneously, may you should add the PID to this string.
