My $HOME/tmp directory got a bit messy, especially with building test rpms or testing tarballs. My solution was to just change the directory to automatically change daily. Scripts below:
:: whot@yabbi:~> cat scripts/tmp-today
#!/bin/bash
date=`date +%Y-%m-%d-%a`
tmpdir=$HOME/tmp/$date
tmplink=$HOME/tmp/today
if [ -e "$tmpdir" ]; then
exit 0
fi
mkdir $tmpdir
ln -sf $tmpdir $tmplink
And the crontab entries to run this script:
0 2 * * * /home/whot/scripts/tmp-today
@reboot /home/whot/scripts/tmp-today
So run the thing at 2.00 am and on every reboot in case the box was shut off overnight.
I had it on midnight first, but I think 2 am is better. If I'm still up at 2 and working, then mentally I'm still in on the day before and I don't want files to end up in different directories just because midnight clocked over.
And because the laptop may be suspended overnight, we run the script on resume as well:
:: whot@yabbi:~> cat /etc/pm/sleep.d/00-tmp-dir
#!/bin/bash
case "$1" in
thaw|resume)
su -c - whot /home/whot/scripts/tmp-today
;;
*)
;;
esac
This obviously works for other directories as well, e.g. your daily download directory.
If you use the polyinstantion namespace feature in pam_namespace - you should be able to have your system automatically do this tmpdir creation for you.
ReplyDeleteHere's a similar solution that I've been using for a few years (placed in my .zshrc file). Type 't' to jump to today's temp directory, 'tp' to print the directory (useful for redirecting logs), and e.g. 't 2' to jump to the directory from the day before yesterday.
