CPU & Memory Redirect Variable Value to a File
I have shell script generate.sh that has
var="HP-UX"

I am following example 19-8 in the below document.

Here Documents

The output.txt is generated however I want the value of variable var to be reflected in the contents of the output.txt file

Code:
cat <<'EOF' #!/bin/bash
connect("Welcome to  /tmp/os/$var")

Current output:

more output.txt
Quote:
cat <<'EOF' #!/bin/bash
connect("Welcome to /tmp/os/$var")
Desired output:

Quote:
cat <<'EOF' #!/bin/bash
connect("Welcome to /tmp/os/HP-UX")
Need your help fix this.

Hi, don't use the ' (single quote) around EOFfor translate the variable value:

Code:
cat <<EOF
#!/bin/bash
connect("Welcome to /tmp/os/$var")
etc...
EOF
