Hi,
Excuse my ignorance here - I'm a networks man and my knowledge of all things unix is somewhat limited.
We have a very large file (/var/tmp/mond.log) that we need to zero - does the "cat /dev/null > /var/tmp/mond.log" command achieve this? (4 Replies)
Hello,
I am working on a script to measure the read performance of a busybox environment. The logical choice is to use a command line like:
(time cp * /dev/null) 2> /tmp/howlong.txt
Ah, the rub is cp or /dev/null will only accept a single file at a time.
The result in the txt file is and... (1 Reply)
I stumbled across a somewhat strange behavior of tar and find no explanation for it: i was testing a DVD for read errors and thought to simply tar the content and direct the output to /dev/null:
tar -cvf - /my/mountpoint/*ts > /dev/null
This way i expected the system to read the complete... (4 Replies)
How are these two different? They both prevent output and error from being displayed. I don't see the use of the "&"
echo "hello" > /dev/null 2>&1

APSFILTER-BUG(1) BSD General Commands Manual APSFILTER-BUG(1)NAME
apsfilter-bug -- create a half-automatic bug report for apsfilter
SYNOPSIS
apsfilter-bug
OPTIONS
none
DESCRIPTION
With the apsfilter-bug script you can automatically create a bug report for apsfilter(1). A template report file is created which you can
edit with your favourite editor ( emacs(1) by default, or whatever is entered in the environment variable EDITOR ).
You will see a couple of lines starting with '#'; these lines will be removed before the report is sent. So if you want to use the '#' char-
acter at the beginning of a line, just indent it with a space.
A very important piece of the bug report is the debugging log created by aps2file(1), probably with a command like
aps2file -D -o /dev/null [-P...] [-Z...] [input] 2> log.txt
Unless you don't even have a chance to create a debugging log, it is crucial for serious bug hunting.
After you have filled in as much (useful) information as possible, you must save the file under its original name, then exit your editor.
If you invoked apsfilter-bug by accident, or if you need some additional system information to include into the bug report, just exit your
editor without saving the file.
NOTES
In addition to the stuff you've edited, some more information is appended to the bug report automatically:
apsfilter version 7.2.6-stable
ghostscript version (from 'gs --version')
system id (from 'uname -a')
configure options --prefix=/usr --sysconfdir=/etc --mandir=/usr/share/man --with-awk=/usr/bin/awk --with-sendmail=/usr/sbin/sendmail
shell executable /bin/bash
awk executable /usr/bin/awk
sendmail executable /usr/sbin/sendmail
FILES
/usr/bin/aps2file script to create debugging output
SEE ALSO apsfilter(1), aps2file(1)BUGS
See apsfilter software center - http://www.apsfilter.org/ - for new versions, bugfixes and known bugs.
Please use the new tool apsfilter-bug(1) to release bug- or problem reports. It automatically presents you a form in an editor window which
asks you some standard questions. If you save and quit the editor session, then this report is sent automatically via e-mail to the proper
apsfilter mailinglist.
If apsfilter fails to print something or prints it in a way you wouldn't expect and you want to report an apsfilter error then please save
the debugging output of one print session using the new aps2file(1) utility by typing aps2file -D -Z options file > /dev/null 2> file.debug
and including the debugging output in the file file.debug into the edit session of the apsfilter-bug utility, so that it is included into the
mail to the apsfilter mailinglist.
Please note that you need to run /bin/sh (Bourne Shell), bash or a compatible shell, so that the above mentioned output redirection works.
Under C-shell (/bin/csh) or tcsh it would't work. If you don't know, then simply make sure you use the Bournce shell by typing /bin/sh or
bash, then you should have no problems with redirection of stdout and stderr (> /dev/null 2> file.debug).
