I need to run a Bash script that can echo a 300 lines of Groovy script to a tmp file. What's the best way to do it ?
My current workaround is putting the script file online and download it.

To add multiple lines to a file with echo, use the -e option and separate each line with \n. When you use the -e option, it tells echo to evaluate backslash characters such as \n for new line. If you cat the file, you will realize that each entry is added on a new line immediately after the existing content.
The echo command is used to display a line of text that is passed in as an argument. This is a bash command that is mostly used in shell scripts to output status to the screen or to a file.
Using '>>' with 'echo' command appends a line to a file. Another way is to use 'echo,' pipe(|), and 'tee' commands to add content to a file.
Use the heredoc syntax to embed the other script within a shell script:
cat > file.tmp <<'endmsg' script goes here... endmsg If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
