I've written a bash script auto.sh. I want this script to accept few command line parameters like some file names or values etc and then use them in my script somewhere.
Sol: So here is what I found to be useful:
if test $# -lt 2 ; then
echo "Need 2 Arguments"
The above basically tests how many command line arguments have been passed. You can see that here it compares it with 2. So basically there are 2 arguments that are required.
$# -> Tells Number of arguments passed
To use the arguments:
$1 --> First argument
$2 and so on..... --> Second argument
If you simply do an echo $1 and echo $2 it will print the command line arguments that you have passed to ./auto.sh.
