Linux – How can I change the default crontab editor

For sh based shells:

export EDITOR=/path/to/nano

For C shell based:

setenv EDITOR /path/to/nano

Remember that unless you save these setting to your login profile script (/home/user/.bash_profile for example), you lose the setting at log out.

If I remember correctly, FreeBSD uses C shell as the default user shell.

As of GNU coreutils 7.5 released in August 2009, sort allows a -h parameter, which allows numeric suffixes of the kind produced by du -h:

du -hs * | sort -h

If you are using a sort that does not support -h, you can install GNU Coreutils. E.g. on an older Mac OS X:

brew install coreutils
du -hs * | gsort -h

From sort manual:

-h, --human-numeric-sort compare human readable numbers (e.g., 2K 1G)
