Pattern: Use of empty string as command name
Issue: -
ShellCheck found an empty string used as a command name. This is never valid.
If the command is intended to do nothing, use true aka : instead. Otherwise, determine why an empty string ended up as a command name and fix it accordingly. In the example, each line was interpreted as a separate command due to missing line continuations.
Example of incorrect code:
jq
''
file.json
Example of correct code:
jq \
'' \
file.json
