That's easy:

    [johnc at dropbear ~]$ ls -1d /home/[a-m]*
    /home/alexz
    /home/caseya
    /home/eloff
    /home/gabea
    /home/gregk
    /home/jamest
    /home/jimb
    /home/johnc
    /home/lost+found
    /home/markg

-1 means print one file/directory per line; -d means list directory
names instead of their contents.

If you want directories only, try:

    [johnc at dropbear ~]$ find /home/ -type d -maxdepth 1 -name '[a-m]*'
    /home/lost+found
    /home/johnc
    /home/markg
    /home/jamest
    /home/gregk
    /home/caseya
    /home/gabea
    /home/eloff
    /home/jimb
    /home/alexz

find doesn't sort names (pipe the output to sort if you want sorted
names).  ls sorts by default (add -U if you want unsorted names).


Cheers,

John

thank you. Been there, done that, got the free coupons, CDroms, lists of
