Shell Programming and Scripting

Hello All,

Not sure why this is happening...

When the following If Statement is evaluated for some reason it is creating a file in the CWD called '0'. I've seen this happen
before, just not in an If Statement...

CODE:

Code:

if [ $# > 0 ]
 then
    DIR_NAME="$1"
    DIR_SIZE=0
    STATUS=""

else
    echo "ERROR: No Arguments were found."
    exit 3

fi

If anyone knows why my Relational Expression of the If Statement seems to be redirecting output to '0',
instead of just evaluating the expression, please feel free to reply...


Thanks in Advance,
Matt

Code:

if [ $# -gt 0 ]

> means file redirection in shell language.

Code:

echo "hello world" > file

If you want to compare integers in shell within [ ], that is -gt, -lt, -ge, -le, -eq.

Code:

if [ "$#" -gt 0 ]
then
...
else
...
fi

But personally, I'd do it like this:

Code:

if [ "$#" -eq 0 ]
then
        echo "not enough arguments"
        exit 1
fi

echo "other stuff"

So that you don't need to track as many if/else/fi blocks and do much less indenting in the 99% of your program that's going to be outside your error code.

Hey bipinajith and Corona688, thanks for your replies...

DUHH.... Thanks, that just completely slipped my mind.
I knew it had to be something little I was overlooking...


Thanks Again,
Matt
