Programming :: How To Redirect ALL Output To (log) File?
Aug 6, 2010
I am again struggling to make a script work, but hey, it is fun, I am learning new things. I discovered the set -x option which was, for me, like the second coming. Still, what I am not able to do is redirect ALL output to a (log) file, including what is produced by the -x setting. Let's assume a very simple script:
Code: #!/bin/bash
set -x
source="/home/atelier/Bureau/"
ls -la $source and I am running it as . test.sh >> /var/log/test.rmcb.log
The result of ls goes inded into the log file, but the rest still shows on the console where I am running the script: Code: ++ source=/home/atelier/Bureau/
++ ls --color=auto -la /home/atelier/Bureau/ Is there a way to redirect EVERYTHING to the log file ?

I am trying to grep multiple numbers from file, grep does have the -f option for that.
Code: grep -f <`seq 500 520` /etc/passwd I know this could be done with
Code: for i in `seq 500 520`; do grep "$i" /etc/passwd; done But my question is fare more behind this example. It is possible to redirect one command output which will be treat as a content of file for another command ?

I have got a script with an outer and inner loop. The inner loop issues loads of echo's which need to be redirected to a log file determined by the outer loop. The obvious solution is to redirect every echo to >$LOG and set LOG in the outer loop.
Code:
for f in $FILES ; do
LOG=<logfile>
for l in $LINES ; do
[code]....
it is possible to map stdout to $LOG in the outer loop without having to redirect every subsequent individual command output?

I would really like to capture the output of scp and my file's progress. Scp updates the transfer rate every 1 second, and I will like to save the transfer rate at every update. So for example, if the file transfer takes 30 seconds, I would like 30 reports of the transfer rate.
The output looks like:
Code:
file.dat 1% 3664KB 938.5KB/s 05:48
Whenever I try a simple redirect like:
Code:
scp file.dat 192.168.1.100:~/ &> output
... it does not save the rate at every update, it only shows the final rate.
If I try using typescript by starting "script" ... it's the same deal.

I want to redirect the output of a command to a file, but not at the end of the file, but after a line. Do you know how can I do it?
Something like:
cat file_a | grep some_text >> resulting_file
# in this file I need to place the output from grep, but not at the bottom of resulting_file, like it would normally happen, but after line .. 3 , for example
Then, if file_a is:
abc x
some_text q
zxc w
[Code]....

I'd like to redirect the output to a file and to the console. I know about tee but the issue is that it waits until the first process finishes.e.gecho "hello world" | tee test.txtfirst calls echo and then tee.Is there a way to redirect "on the fly" ?

I was trying to redirect the output of two variables to different columns of a .csv file in MS excel like this,
Code:
echo "$a $b" > abc.csv
But I am getting both $a and $b in the same column, is there anything I can use instead of to move the value of $b to the next column? Or is there a good different approach to do it?

To redirect standard output to multiple files:
Code:
echo Test | tee file1 file2
My problem is that the word "Test" still displays to the screen? I want same effect as:
Code:
echo Test > file1
but with multiple file redirection.

Ubuntu 10.04
I booted to command line only and entered the following command: Sudo Xorg -configure > xorglog.txt
the command seems to run just fine and does create a new xorg.conf.new file but I would like to see all the output of the Xorg -configure command but it just scrolls by too fast and I can't go back to see it. Hence this is why I'm trying to do the > . It seems to ignore the >.
how I can see what the command is doing?

I wrote a short script that sleeps for 30 seconds then outputs "Done" to the screen:
sleep 30
echo Done
now I want to re-direct the output to a file, I tried:
./scriptName& > fileName
Didn't work, "Done" still came out to the screen.

I have a python script that when run outputs to screen.
eg.
./international_sms_check.py 0403000511 919227434827
TS 21 check ok
TS 22 check ok
sms successfully delivered from 61403000511 to 919227434827
But when I try:./international_sms_check.py 0403000511 919227434827 > test
The file test is created but there is nothing in it.if I try ls > test this works fine with output of ls redirected to file test.

I'm working on some scheduled task script files to keep nightly backups of some of our database information in place, and it's a bit annoying when they blow up. I know how to redirect stdout and stderr to a flat file I can view when I come in, and I know that 2>&1 maps them both to the same file (whatever was named in 1). However, I'm running into some cron-time situations where it's easier to have the two streams together, and other cron-time situations where it's easier to have them separated. I can't really tell which is going to happen; is there some way I could create both kinds of output file for my scripts, so that I've got a std_err only file and an interleaved std_out/std_err file?
Note: I've looked at the 'tee' command, but I don't think it will work for what I'm after. 'tee' appears to only work with stdout; I'm trying to work with stderr.

Is there one command that will let me record an entire terminal session (with any possible errors) to a text file while also seeing all output on screen too? I know it can be done for individual commands, but I'm looking to do this for an entire session where the individual commands will be normal (i.e., not piped into tee, etc.). It would be even better if the command prompt is captured too. The obvious utility of this makes me think someone surely has come up with a solution long ago (probably in the 60's).(I'm sure it goes without saying, but subsequent output in that session should be appended to the file. The file should contain the full history, with all output and errors, of the session.)

I have a set of bash scripts that I'm running that automatically build a set of packages for me and redirect their output into logs. Basically, I have a bunch of lines that are something like this: ${CONFIGURE_DIR}/configure &> ${LOG_DIR}/log or cd ${CONFIGURE_DIR} && make &> ${LOG_DIR}/log, etc.
This is supposed to make the entire process silent. However, sometimes with some packages some output leaks to my console (either stdout or stderr). I'm thinking that maybe the configure scripts/make are executing commands within new shell instances that don't inherit my redirect, or something to that effect.
Another reason for thinking this is that in another part of my script I detect errors when running make by testing with "if [ $? -ne 0 ]", and if the redirect leaks to my console and also the leaked output indicates that the build failed ("make: Error" and so on), then my $? test fails (i.e., it thinks that $? == 0, whereas a failed make should return a non-zero value). It's as if my original script can't "see" the results from child commands executed from later scripts.

I have a little complex Makefile system. A parent Makefile call dozens of Makefiles in subdirctories. And the subdirctory Makefile calles shell script to do real building. I want to grab all output this Makefile system generate. So, i employ "make 2>&1 > make.log". but not all output messages are filed into make.log. The message generated by sub-makefile called shell script cannot be recorded into make.log. And another curiouse thing is, if i launch "make 2>&1 > make.log" in a perl script, all output do be sent into make.log.

I have recently merged two Joomla 1.0 sites I ran into one. I imported the articles I wanted to keep to the new site, and I have the old site's domain pointing as an alias at the new site. The new site is www.theouthousers.com . The old site was www.bludblood.com .
I also have the core SEF URLs on, using the htaccess.txt file that came with Joomla.
I have one writer for the old site who linked to his articles in various places, so I am trying to set up redirects for him so that he doesn't have to change all of his links.
For instance, I need something like:
http://www.bludblood.com/joomla/inde...d=25&Itemid=51
To redirect to the equivalent location on the new site:
[url]
And I also need specific links like:
[url]
To redirect to their new counterparts:
[url]
Keeping in mind that www.bludblood.com is now an alias of www.theouthousers.com, is there any way to do this? I have been trying with rewrite rules and redirects, and cannot seem to achieve the desired effect.
Tried various versions of:
Code:
Redirect [url] [url]
With the http, without, as regexps, as 301s, as permanents, etc, and it just will not work. Also tried as RewriteRule.

My employer issues pdf files with everyones work schedules. I copy the content and save it as plain text in a file called unformatted (hope to be able to automate this step someday). Im working on a SED script that reduces unformatted to only display what I want to see and saves the result in a file Iïve named formatted. After that I have to manually copy formatted and save it with that days date as a filename e.g. 2011-02-25 or whatever day is scheduled in the pdf, for use on a mobile device (Nokia N900). I noticed that the date occurs on certain lines in the file so I added a line like:
sed -n 's/^Date: (201[1-9])/([0-1][0-9])/([0-3][0-9]).*/1-2-3/p' < unformatted >theDate
That creates a file theDate with the date in it that I wish to use as the filename for this particular instance. So I would like to skip the file formatted all together and have the sed- script write to a new file using the content of the Date as a filename, but how do I make that happen? And of course it would be more elegant if I could skip the intermediate theDate file as well.

if I'm posting to the wrong forum. Be so kind to tell me where to better ask this question, as I'm really not finding the right words to google for.So, I have a shell application (fdb) which is a Flash debugger. I want to run it using bash script, capture it's output and pass it the commands (it can read from STDIN). The reason I want to do so is that Flash Builder (the IDE for Flash development) is plain stupid when it comes to compilation, and it won't allow me to compile any file in the project... so, I found out that I can make Eclipse to run an external tool. This external tool is my *.sh file whichches the compiler, and then it launches the debugger.The Eclipse console can display the compilation results, or errors. When I run the debugger it can even pass the input from Eclipse console to the debugger, however, the output from the debugger isn't shown.
