Which PATH variable should I use for this scirpt?

whichpath() { local -A path; local c p; for c; do p=$(type -P "$c"); p=${p%/*}; path[${p:-/}]=1; done; local IFS=:; printf '%s\n' "${!path[*]}"; }

I find it useful when I want to add another crontab entry and I need to specify the appropriate PATH. I give ''whichpath'' a list of programs that I use inside my script and it gives me the PATH I need to use for this script. ''whichpath'' uses associative array, therefore you should have Bash v4 in order to run it. See sample output.

Sample Output

rany:~$ whichpath md5sum cat ls nc sat
/bin:/home/rany/bin:/usr/bin
rany:~$

Approssimativamente, e considerando che le tariffe delle scuola guide possono anche di molto, il costo finale per una patent B if aggira in media sui 1.200 euro, considering corsi completi e qualche ora di guida in più rispetto a que obligatorie che come abbiamo detto sono molto spesso insufficienti. La patente di guida categoria B, detta anche patente internazionale, permette di guidare tutti i veicoli di massa non superiore a 3.500 kg, esclusi i motoveicoli, le ciclomotori e i ciclomotori a due ruote.
