提问by coffeemonitor
I created a simple shell script:
I created a simple shell script:
#!/bin/bash
clear
echo "Starting Script now....."
echo "Write the info below to a new file in same directory...."
echo "name: John Smith"
echo "email: [email protected]
echo "gender: M"
echo
echo
echo "File is done"
I want to create a file in the same directory with the Name, email, and gender details. I don't want to do it from the command line like this:

I'd rather do it from within the file itself.

For all your echo "name:John Smith"lines add a > $1(ie first parameter passed in to the script).

Then run the script like ./script.sh my.config.
Then run the script like ./script.sh my.config.
Or you could replace the $1with my.configand just run ./script.sh.
