When I go to change a configuration file I always like to make a backup first. You can use "cp -p" to preserve the modification time, but it gets confusing to have file.prev, file.prev2, etc. So I like to add a YYMMDD suffix that shows when the file was last changed. "stat -c %Y" gives you the modification time in epoch seconds, then "date -d @" converts that to whatever format you specify in your "+format" string. Show Sample Output
3cp file file.$(date -d @$(stat -c '%Y' file) "+%y%m%d") -
The simpler, 1-arg version is save_function(){ { date +"# %F.%T $1; declare -f "$1";}| tee -a ~/.bash_functions; }` Show Sample Output
2save_function(){ while [[ $# > 0 ]]; do { date +"# %F.%T $1; declare -f "$1";}| tee -a ~/.bash_functions; shift; done;} -
fstrim is usually used on SSDs but can also be used to remove useless bits from file system images. This is most helpful if the compressed disk image is intended to be distributed, since it will be smaller than an untrimmed compressed image. Show Sample Output
0kpartx -av disk.img && mkdir disk && mount /dev/mapper/loop0p1 disk && fstrim -v disk && umount disk && kpartx -d disk.img - ‹ First < 3 4 5 6 7 > Last ›
