This is a simple utility to print the entries from your PATH environment variable in a tabular format with indicators for invalid and duplicate entries.
By default it prints the PATH variable entries. But you can specify any other variable you want.
$ prtpath
Index Status Path
1 dir /Users/me/Applications/miniconda3/condabin
2 dir /Users/me/.nvm/versions/node/v14.17.3/bin
3 dir /usr/local/bin
4 dir /usr/bin
5 dir /bin
6 dir /usr/sbin
7 dir /sbin
8 dir /Library/TeX/texbin
It can sniff out things like duplicate directories or malformed entries. For example, if I add the following two entries to the front of the PATH:
/usr/bin/- a duplicate of entry 4 above (even though one ends with a/and the other doesn't),/usr/blah- a path which doesn't exist,
the output shows:
$ prtpath
Index Status Path
1 dir /usr/bin/
2 -invalid- /usr/blah
3 dir /Users/me/.nvm/versions/node/v14.17.3/bin
4 dir /Users/me/Applications/miniconda3/condabin
5 dir /usr/local/bin
6 -dup----- /usr/bin
7 dir /bin
8 dir /usr/sbin
9 dir /sbin
10 dir /Library/TeX/texbin
Entry 2 is invalid and entry 6 becomes a duplicate of entry 1.
You can specify any other variable you'd like.
