Two leading slashes, such as //foo, may be the odd one out depending on system.

If this script is bash only, you could use bash parameter expansion to get rid of any number of //:

$ DIR="/long//numerous//doubleslashed/path/to/"
$ FILE="file"
$ MYPATH="$DIR/$FILE"
$ cd $MYPATH
bash: cd: /long//numerous//doubleslashed/path/to//file: No such file or directory
$ cd ${MYPATH//\/\//\/}
bash: cd: /long/numerous/doubleslashed/path/to/file: No such file or directory

See http://mywiki.wooledge.org/BashGuide/Pa … _Expansion if you want a better explanation.

Edit: changed variable name from PATH to MYPATH.  Boy was I surprised by bash: pacman: command not found

But whether the Constitution really be one thing, or another, this much is certain - that it has either authorized such a government as we have had, or has been powerless to prevent it. In either case, it is unfit to exist.
