When I run this script on my terminal it works perfectly with the newline
echo -e $(echo "a \na")
Outputs:
a
a
When I wrap this up in a bash script - test.sh:
#!/bin/sh
echo -e $(echo "a \na")
And I call ./test.sh, I get this output:
-e a a
How can I make the bash script give the same output with the newline as running directly on the terminal?
Use printf. The echo isn't portable. Some shells doesn't knows the -e and like. Also, using printf you will get more formatting options.
printf "%s\n%s\n" a a
#or
printf "a\na\n"
The answer to your question is in the @that other guy's comment:
Make the shebang #!/bin/bash, otherwise it's a sh script and not a bash script
e.g.
sh test.sh
# -e a a
bash test.sh
# a
# a
dash test.sh
# -e a a
zsh test.sh
# a a
so... use printf - will work everywhere and give the same result.
