I'm using the linux 'script' command [URL]... to track some interactive sessions. The output files from that contain unprintable characters, including my backspace keystrokes.
Is there a way to tidy these output files up so they only contain what was displayed on screen?
Or is there another way to record an interactive shell session (input and output)?
I'm writing a script that gives me some pertinent info about my servers, and the last little piece I need to figure out is the process list. There are going to be non-technical people looking at the output of the script and I'm trying to make it as simple as possible.
Right now, if I do ps -ef | grep <process> | grep -v grep
It obviously shows me the process, but the problem is that there is 4 lines of info in front of the process. ie
root PID date time java -1024 -cp oh,my,god,there,is,so,much,data,it,carries,on,for,4,lines,I,want,to,shoot,myself,trying,to,read,it,f inally,in,the,end,there,is,a,space /here/is/the/process
I'd like the output to be something like this:
PID: #### Process: /here/is/the/process
I've thought about how I could take the output and use awk or sed but I know there is probably an easier way to do it with perl.
Wondering how to use awk to take nmap's output "Discovered open port 23/tcp on 192.168.0.4" and create a output of "192.168.0.4:23"?

I am using openSUSE 10.3.When I install software from tarball then to record time required I send output of date to beg.txt(when installation begins) and end.txt (when installation finishes).How can I append output of date to a file so I don't need two files?
View 4 Replies View RelatedI have wrote a 1 line command that parses a file, locates the IP Address in the file and then trims the output the way I want it, and then sorts numerically and by uniqueness and then >> appends to output.txt
I can get all the IP's into 1 file "output.txt", but what I am really looking for is some type of way to create a text file, for each IP it finds labeled xxx.xxx.xxx.xxx.txt and also put that ip address into that file..
xxx.xxx.xxx.xxx = the ip address it finds

View 4 Replies View RelatedI have a Gigabyte 6A-M61P-S3 with an nVidia chipset, and I'm using the built-in graphics rather than a discrete graphics card. Ubuntu 10.10 and previous releases ran flawlessly on it using the nouveau drivers. I tried doing an upgrade to 11.04 using the Alternate AMD-64 CD, and it seemed to complete successfully, but when it came time to reboot, I had no video output at all after the BIOS screen. This is a test machine, so I went ahead and did a clean install using encrypted LVM with the Alternate AMD-64 CD after confirming that 64-bit 11.04 ran fine using the Live CD.
The installation went fine, but the first reboot flashed a brief "error: no video mode activated" and then I lost all video output. Subsequent reboots didn't give me any error message, but I had no video output. I suspect there are some boot parameters that would have gotten the nouveau driver working, but I wanted to try Unity, so I rebooted to get the Grub menu, chose Recover Mode, selected failsafe graphics, and got to the Desktop, then installed the proprietary nVidia driver (current) and once I rebooted everything was golden.

I have a script that is in Unix. I wanted to know is there any difference between output of ls command in unix and linux
In Unix
Code:
ls -ltr | awk '{print $9}'
In linux output is something similar to
Code:
drwxrwxrwx 2 vinay vinay 4096 2010-02-04 20:31 test
According to above output nothing will be displayed for
Code:
ls -ltr | awk '{print $9}'
ls -ltr | awk '{print $8}' will give test as ouptut in Linux.
I wanted to check the output format for ls -ltr, Anyone using Unix systems may paste a sample output of the command ls -ltr..

I need to create a zip file of jpg and bmp files. The zip file is named after the first file it finds which ends with .dat. Here is my script:
Code:
DAT_FILE= `find . -maxdepth 1 -iname "*.dat" | head -1 | sed 's/..(.*)..../1/'`
(cd pics; find . ( -name "*.bmp" -o -name "*.jpg" ) -print | zip ../$DAT_FILE -@ )
BTW my sed command cut off the first two chars and last four chars since find will return the filename is the form of "./filename.dat" and I just want to extract filename. When I run this script, it creates a zip file named ".zip". How do I fix this so the zip file is named after my dat file?

What Linux command can do this?
This seems so simple when doing it from command line but I'm not able to accomplish it inside a script. I am trying to put output of following command into a text file:
CMD= mysql -uroot -psecret -e 'SHOW SLAVE STATUS G;'
FIL=~/replication-`date +%F`.txt
MAILTEXT=~/mailtext.txt
touch $FIL
$CMD > $FIL
Where FIL is a variable that contains path of the file to which to output command. I am running this command in a shell script from where I want to email contents of $FIL as attachment using mutt. But I am always getting 0 byte file. Also if I examine in directory the file is of 0 byte length.
