SC2043

This loop will only run once, with var=value

Problematic code:

for var in value
do
  echo "$var"
done

Correct code:

Correct code depends on what you want to do.

To iterate over files in a directory, instead of for var in /my/dir use:

for var in /my/dir/* ; do echo "$var"; done

To iterate over lines in a file or command output, use a while read loop instead:

mycommand | while IFS= read -r line; do echo "$line"; done

To iterate over words written to a command or function's stdout, instead of for var in myfunction, use

for var in $(myfunction); do echo "$var"; done

To iterate over words in a variable, instead of for var in myvariable, use

for var in $myvariable; do echo "$var"; done

Rationale:

ShellCheck has detected that your for loop iterates over a single, constant value. This is most likely a bug in your code, caused by you not expanding the value in the way you want.
