This will send every line that anything prints into standard ouptut, into the logfile.
And to send both stdout and stderr to logfile for all commands in the script that don't otherwise redirect their output, you can use:
and, of course if you want to append to an existing logfile instead of overwriting it, you can use:

logtail
LOGTAIL(8) logtail manual LOGTAIL(8)NAME
logtail - print log file lines that have not been read
SYNOPSIS
logtail [-t] -flogfile [-ooffsetfile]
DESCRIPTION
logtail reads a specified file (usually a log file) and writes to the standard output that part of it which has not been read by previous
runs of logtail. It prints the appropriate number of bytes from the end of logfile, assuming that all changes that are made to it are to
add new characters to it.
logfile must be a plain file. A symlink is not allowed.
logtail stores the information about how much of it has already been read in a separate file called offsetfile. offsetfile can be omitted.
If omitted, the file named logfile.offset in the same directory which contains logfile is used by default.
If offsetfile is not empty, the inode of logfile is checked. If the inode is changed, logtail simply prints the entire file. If the inode
is not changed but logfile is shorter than it was at the last run of logtail, it writes a warning message to the standard output.
OPTIONS -f logfile to be read after offset
-o offsetfile stores offset of previous run
-t test mode - do not change offset in offsetfile
RETURN VALUES
0 successful
65 cannot get the size of logfile
66 logfile does not exist, is not a plain file, or is not readable
73 cannot write offsetfile
