tar the current directory wihtout the absolute path

tars the current directory (and its children) in an archive of the same name (plus ".tar" :)) in the parent directory without the absolute path, so that when the archive is extracted, only the current directory name is created for the path. Assumes bash/zsh.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
tar -cf "../${PWD##*/}.tar" .

should do the same as command #12875, just shorter.

Know a better way?

If you can do better, submit your command here.

What others think

Hmm... An example might help people understand better.

I had to try out the command to be certain what it did :-)

I can think of two shorter ways of getting the same result:

(D=${PWD##*/}; cd ..; tar cf "$D.tar" "$D")

In a subshell (), find our directory name ($D), go up one directory and create a tar file.

The subshell means that tar is run in .. but we stay where we were.

The alternative (if you don't mind a harmless tar warning) is:

D=${PWD##*/}; tar cf "../$D.tar" "../$D"

tar will warn you about, but ignore, the leading ../

Note: I have quoted all the paths just in case the directory name contains whitespace.

I'm curious what's wrong with giving the path of '..' for parent dir to tar? Something like:

D=${PWD##*/} ; tar -C .. -cf "../$D.tar" "$D"
Comment by pdxdoughnut 44 weeks and 6 days ago

You can shorten this to: tar -cf ../$(basename $PWD).tar .

Comment by joedhon 44 weeks and 4 days ago

pdxdoughnut's version is probably optimal (shorter than my proposed version). joedhon's version, however, doesn't preserve the current folder name without the above path which was the whole point of my original command.
