Creating a shell script inside a text editor
I want to know how to create a shell script inside a text editor.
So this is what I have inside the text editor.
#!/bin/bash
mkdir -p temp
cd temp
if [ $1 > $2 ] ;
then
echo $1
else
echo $2
fi
./max.sh 4 6
./max.sh -2 -5
./max.sh 7 -3
So basically inside the text editor I want to create a shell script called max.sh so that below it I can pass arguments through it but in the same text editor.
To make it more clear:
I want the if-statement to be inside a script called max.sh, so below it I can call the max.sh with arguments and it will work.
bash shell-script

What you want is called a function:
#!/bin/bash
max() {
if [ "$1" -gt "$2" ] ;
then
printf %s\n "$1"
else
printf %s\n "$2"
fi
}
max 4 6
max -2 -5
max 7 -3
Further reading:
- In Bash, when to alias, when to script, and when to write a function?
- Why is printf better than echo?
- Why does my shell script choke on whitespace or other special characters?

You can do what you ask like this:
#!/bin/bash
mkdir -p temp
cd temp
cat <<_script_lines_ > max.sh
#!/bin/bash
if [ "$1" -gt "$2" ] ;
then
printf '%sn' "$1"
else
printf '%sn' "$2"
fi
_script_lines_
chmod u+x max.sh ### make the script excutable.
# Use the script:
./max.sh 4 6
./max.sh -2 -5
./max.sh 7 -3
But the function already recommended by Wildcard seems more reasonable to use.
this works as well, thanks for the suggestion, appreciate it

@shawnedward, do be careful with this if you use it, though—a fixed name temp file is a security hole.
