Pattern: Use of echo with escape sequence
Issue: -
Backslash escapes like \t and \n are not expanded by echo, and become literal backslash-t, backslash-n.
printf does expand these sequences, and should be used instead.
Other, non-portable methods include echo -e '\t' and echo $'\t'. This rule will warn if this is used in a script with shebang #!/bin/sh.
If you actually wanted a literal backslash-t, use
echo "\\t"Example of incorrect code:
echo "Name:\t$value"Example of correct code:
printf "Name:\t%s\n" "$value"
