what does while [ -h "$SRP" ]


Trying to learn shell scripting here. I figured out the while loop and and the $SRP variable part. But google or other forums did not help me understand what -h stands for. Anyone can help?

Also where can I find more info on other arguments for while similar to -h?

Thanks !

The '[' character is a shorthand for the test command.

man test gives this explanation for the -h option:
Quote:
-h FILE
FILE exists and is a symbolic link (same as -L)
