[TynesideLUG] bash script - writing log file entries

[Ian Bruntlett]

Hi,

>From a conversation elsewhere, I came up with this shell script I called
expt-logging:-

#!/usr/bin/env bash
echo Normal standard output aka stdout or cout
echo Logging output aka stderr or cerr >&2
echo End of stdout

Here are the results of running it normally..
$ ./expt-logging
Normal standard output aka stdout or cout
Logging output aka stderr or cerr
End of stdout

Here are the results of sending stderr (fiie descriptor 2) to stdout (file
descriptor 1):-

$ ./expt-logging 2> /dev/null
Normal standard output aka stdout or cout
End of stdout

HTH,


Ian
