The problem is, 'time' is not an external command, it is a builtin, and one that doesn't seem to obey normal redirection either! I had to wrap it in brackets to get the shell to catch it.
Code:
( time wget -q sitename -O /dev/null ) 2> wlog
wget's built-in -q is easier than > /dev/null 2> /dev/null, and -O /dev/null stops it from cluttering your current directory with downloaded files.
thank you!, I may have head of hair left after I finish this script after all
This was driving me nuts! and the -O option is nice.. I was palnning on rm'ing the downloaded file afterwards... now I dont have to.
In bash, I need to send the STDOUT and STDERR from a command to one file, and then just STDERR to another file. Doing one or the other using redirects is easy, but trying to do both at once is a bit tricky. Anyone have any ideas? (9 Replies)
If I forget to set up stderr redirection on execution of a script, is there a way to set that redirection post-exec? In other words, if I have a script running and no errors are being logged... and then I remember that I forgot the 2>&1 on the script... can I turn it on after the fact?

Friends
I have to redirect STDERR messages both to screen and also capture the same in a file.
2 > &1 | tee file works but it also displays the non error messages to file, while i only need error messages.
Can anyone help?? (10 Replies)
Doubt regarding using "exec" command to redirect the STDERR to a file. e.g I did it this way.

Hi folks
I need/want to redirect output (stdout, stderr) from an exec call to separate files. One for stderr only and two(!) different (!) ones for the combined output of stderr and stdout.
After some research and testing i got this so far :

I know that
mmmmm 2> error.txt
will send the error message to the specified file instead of the screen. However, I have seen
>&2
in some scripts, and I can't get it to do anything. A source said it sends stdout and stderr to a file. What file?

makedev.local
MAKEDEV.LOCAL(8) BSD System Manager's Manual MAKEDEV.LOCAL(8)NAME
MAKEDEV.local -- create site-specific device special files
SYNOPSIS
MAKEDEV.local [-fMsu] [-m mknod] [-p pax] [-t mtree] {all | site-specific-argument} [...]
DESCRIPTION
MAKEDEV.local is used to create site-specific device special files. Each argument may be the word all or a site-specific argument. By
default, there are no valid site-specific arguments, and the all argument has no effect; This may be changed by editing the script.
The script is in /dev/MAKEDEV.local. Devices are created in the current working directory; in normal use, MAKEDEV.local should be invoked
with /dev as the current working directory.
Supported options for MAKEDEV.local are the same as for MAKEDEV(8).
FILES
/dev special device files directory
/dev/MAKEDEV script that invokes MAKEDEV.local with the all argument.
/dev/MAKEDEV.local script described in this man page
SEE ALSO config(1), intro(4), MAKEDEV(8), mknod(8)HISTORY
The MAKEDEV.local command appeared in 4.2BSD. Handling of the same command line options as MAKEDEV(8), and the use of MAKEDEV(8) as a func-
tion library, was added in NetBSD 5.0.
NOTES
The relationship between MAKEDEV.local and MAKEDEV(8) is complex:
o If MAKEDEV(8) is invoked with the all or local argument, then it will invoke MAKEDEV.local as a child process, with options similar to
those that were originally passed to MAKEDEV(8), and with the all argument.
o MAKEDEV.local uses shell functions defined in MAKEDEV(8). This is done by loading MAKEDEV(8) using the shell ``.'' command, with the
MAKEDEV_AS_LIBRARY variable set (to inform MAKEDEV(8) that it should behave as a function library, not as an independent program).
