This works for me where "2>&1" doesn't retain the order of the messages.
For example with unix "traceroute".
The original poster wants two separate logs with stdout and stderr respectively and one with both of them in the correct order.

nice solution with the subshells , but unfortunately this does also not work at all.
This works well if you have outputs to stdout and stderr alternating, but if there is more then one lines written to one of stdout or stderr, the numbering increases for this one, but not for the other one ...
Is there a way to send the syslog output for a given facility to stderr or stdout?
I do not want to use the "tail" command to achieve this, I would like it to go directly to stderr.
Thanks in advance (1 Reply)
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)
This is about getting all output to stderr and stdout localized. Nothing to do with redirecting output to a file (there already are some interesting threads about that issue on this forum).

Friends
I have to redirect STDERR messages both to screen and also capture the same in a file.

Hello all. I've been lurking here for a year or two and finally decided to post.

I have to redirect STDERR messages both to screen and also capture the same in a file but STDOUT only to the same file.

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.

LOG2PCAP(1) User Commands LOG2PCAP(1)NAME
log2pcap - Extract network traces from Samba log files
SYNOPSIS
log2pcap [-h] [-q] [logfile] [pcap_file]
DESCRIPTION
This tool is part of the samba(7) suite.
log2pcap reads in a samba log file and generates a pcap file (readable by most sniffers, such as ethereal or tcpdump) based on the packet
dumps in the log file.
The log file must have a log level of at least 5 to get the SMB header/parameters right, 10 to get the first 512 data bytes of the packet
and 50 to get the whole packet.
OPTIONS -h
If this parameter is specified the output file will be a hex dump, in a format that is readable by the text2pcap utility.
-q
Be quiet. No warning messages about missing or incomplete data will be given.
logfile
Samba log file. log2pcap will try to read the log from stdin if the log file is not specified.
pcap_file
Name of the output file to write the pcap (or hexdump) data to. If this argument is not specified, output data will be written to
stdout.
-?|--help
Print a summary of command line options.
EXAMPLES
Extract all network traffic from all samba log files:
$ log2pcap < /var/log/* > trace.pcap
Convert to pcap using text2pcap:
$ log2pcap -h samba.log | text2pcap -T 139,139 - trace.pcap
VERSION
This man page is correct for version 3 of the Samba suite.
BUGS
Only SMB data is extracted from the samba logs, no LDAP, NetBIOS lookup or other data.
The generated TCP and IP headers don't contain a valid checksum.

The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
