usage: test [-bcdefghLPrSsuwx PATH] [-nz STRING] [-t FD] [X ?? Y]
Return true or false by performing tests. (With no arguments return false.)
--- Tests with a single argument (after the option):
PATH is/has:
-b block device -f regular file -p fifo -u setuid bit
-c char device -g setgid -r read bit -w write bit
-d directory -h symlink -S socket -x execute bit
-e exists -L symlink -s nonzero size
STRING is:
-n nonzero size -z zero size (STRING by itself implies -n)
FD (integer file descriptor) is:
-t a TTY
--- Tests with one argument on each side of an operator:
Two strings:
= are identical != differ
Two integers:
-eq equal -gt first > second -lt first < second
-ne not equal -ge first >= second -le first <= second
--- Modify or combine tests:
! EXPR not (swap true/false) EXPR -a EXPR and (are both true)
( EXPR ) evaluate this first EXPR -o EXPR or (is either true)
