The "date' command has options to easily format the date, day, month, time, etc. But what if you want a relative date or time. Like, I wanted yesterday's date in a particular format. You may want the exact date of "2 months ago" or "-3 days" nicely formatted. For that, you can use this command. The --date option takes fuzzy parameters like the ones mentioned in the previous sentence.

'data' is the directory to backup, 'backup' is directory to store snapshots.

Backup files on a regular basis using hard links. Very efficient, quick. Backup data is directly available.

Same as explained here :


in one line.

Using du to check the size of your backups, the first backup counts for all the space, and other backups only files that have changed.

ls -la | grep $(date +%Y-%m-%d) | egrep -v -e '\.{1,2}' | sed "s/.*\:[0-9]\{2\} \(.\+\)$/\\1/g"

This command prints the Date (Not time) from 3 days ago (72 hours ago).

This works on systems without GNU date (MacOSX , Solaris, FreeBSD).

Change HH:MM with your target time.

This is for a Debian/Ubuntu GNU system. You need bash (package bash), date (package coreutils) and toilet (package toilet). Install with:

# apt-get install bash coreutils toilet toilet-fonts

sleep 8h && while [ 1 ] ; do date "+Good Morning. It is time to wake up. The time is %I %M %p" | espeak -v english -p 0 -s 150 -a 100 ; sleep 1m; done

This ran on a ubuntu box using espeak for speaking text with the bash shell. On a mac you should use 'say'. Also you can change your alarm interval and your snooze interval which are currently 8 hours and 1 minute. I would run this via cron yet it's easier to disable if you run it as a command like this :P

echo $((($(date +%s)-$(date +%s -d "march 1"))/86400))

You can also do this for seconds, minutes, hours, etc... Can't use dates before the epoch, though.

H=$(until ([ $i -le 6 -a $i -gt 0 -o $i -le 23 -a $i -gt 21 ] ); do i=$(date +%N | cut -c8-10); done ; echo $i) ; M=$(until [ $i -le 59 ]; do i=$(date +%N | cut -c8-10); done ; echo $i) ; echo $M $H \* \* \* backup-rsync-push.sh

you will hear how many seconds since 1.1.1970 in english words with billions, millions and thousands.

this is very useful, if you want to get over to use the unixtimestamp instead of the 24 hour clock in your dayly life

touch file-$(date +%Y%m%d)
utime(){ date -d "1970-01-01 GMT $1 seconds"; }

More recent versions of the date command finally have the ability to decode the unix epoch time into a human readable date. This function makes it simple to utilize this feature quickly.

date +%s | sha256sum | base64 | head -c <length>; echo
alias dateh='date --help|sed -n "/^ *%%/,/^ *%Z/p"|while read l;do F=${l/% */}; date +%$F:"|'"'"'${F//%n/ }'"'"'|${l#* }";done|sed "s/\ *|\ */|/g" |column -s "|" -t'

If you have used bash for any scripting, you've used the date command alot. It's perfect for using as a way to create filename's dynamically within aliases,functions, and commands like below.. This is actually an update to my first alias, since a few commenters (below) had good observations on what was wrong with my first command.

# creating a date-based ssh-key for askapache.github.com

ssh-keygen -f ~/.ssh/`date +git-$USER@$HOSTNAME-%m-%d-%g` -C '[email protected]' # /home/gpl/.ssh/[email protected]

# create a tar+gzip backup of the current directory

tar -czf $(date +$HOME/.backups/%m-%d-%g-%R-`sed -u 's/\//#/g' <<< $PWD`.tgz) . # tar -czf /home/gpl/.backups/04-22-10-01:13-#home#gpl#.rr#src.tgz .

I personally find myself having to reference

date --help

quite a bit as a result. So this nice alias saves me a lot of time. This is one bdash mofo. Works in sh and bash (posix), but will likely need to be changed for other shells due to the parameter substitution going on.. Just extend the sed command, I prefer sed to pretty much everything anyways.. but it's always preferable to put in the extra effort to go for as much builtin use as you can. Otherwise it's not a top one-liner, it's a lazyboy recliner.

Here's the old version:

alias dateh='date --help|sed "/^ *%%/,/^ *%Z/!d;s/ \+/ /g"|while read l;do date "+ %${l/% */}_${l/% */}_${l#* }";done|column -s_ -t'

This trick from my [ http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html bash_profile ]

mkdir $(date +%F)
