From the description of
set in the
-v Print shell input lines as they are read.
Thus, the following example script:
#!/usr/bin/env bash # setv.sh set -v foo=bar echo $foo
foo=bar echo $foo bar
Is there a way for it to prepend some string, say "+ " to each line, so as to clearly indicate which line is a line from the script, and which line is output of a line of from the script. Using the above example, the desired output would be:
+ foo=bar + echo $foo bar
