If flag is true, turn debugging on. Otherwise, turn debugging

set -x command to be more verbose.

bourne shell command. The kind variable consists of two letters.
The first letter can be either of '-' (which means the command
reads its standard input), 'f' (which means the commands reads
a given file on the command line) or '.' (which means the commands
reads no input, and hence must be first.)
Similarly, the second letter can be either of '-' (which means
the command writes to standard output), 'f' (which means the
command writes a file on the command line) or '.' (which means
the command does not write anything, and hence must be last.)
-
Add a new action at the beginning. See append() for explanations
of the arguments.

written to by the pipeline. Note that only one of
'r' ,
'w' may be given.
