Use of IF command in the command line.

What is the command line syntax for the if exist command in Unix like in DOS/WIN which test for the existance of a file?

Is the syntax the same in a script?

Thanx

A couple of options

.ksh

if [[-f filename]] for existence

If I can remember correctly...

if [[-s filename]]for non-empty

Does this syntax work on the command line?

I am getting a ">" back from my command.

yeah..., that is the continuation marker.

You can type:

if [[ -f filename]] then [ENTER]
echo "File exists" [ENTER]
else [ENTER]
echo "File does NOT exist" [ENTER]
endif [ENTER]

...and it should respond accordingly
