I have a CSV file with 8 columns. I want to check the 5th column, which will contain a single capitalised letter. If that letter is say "B" I would then like to replace the 2nd column in the csv with an incremental number starting at 0 (basically a count) with a prefix of B (B0000001) Sample row would be:
Code:
C, 0109390,sfs,sfsf,B,blah,blah
Amended row would be:
Code:
C, B000001,sfs,sfsf,B,blah,blah
Can the Replace function replace more than one word with the same character(s)?
Also, do you know how to access the plugins provided by the gedit-plugins package?

I need a script that will replace '/' in a variable with ''I have tried the following:
Code:
y=$(echo $1|sed 's///\/g')
The thing is that this approach does not always work. Here is an example:
Code:

z:usr
arsakis.txt
user@pc:~$ sh script.sh /usr/tar/sakis.txt
z:usr arsakis.txt
Is there a way to treat those characters?
I am bouncing a file across platforms (windows->solaris->mainframe), and the file is starting out with a "special" character (the registered trademark "circle R") in some of the records. This character is not in the EBCDIC character set on the MF, so it is unrecognizable. The MF developer I am working with asked if it is possible to replace the character with a specific hex value (AF) before it gets to the MF.
I was putzing around with sed, tr, etc. on the ksh command line, hoping to find an easy way to get one of them to substitute hex instead of ASCII. I have found that the usual shell utilities recognize the trademark character, so homing in on what to replace is solved. But I cannot get anything to actually substitute in the hex sequence I want. E.g. I was thinking something like...
>cat special_file | sed 's/R/AF/g'
But my version of sed does not seem to have hex "editing" capability.
I want to use SED to do the following: In a text file replace any occurrences of the three character string ZZZ with a quotation mark "and. replace all occurrences of a comma with a semi-colon.

I'm a bit of a Linux newbie, but I did manage to set up the following RAID-5 system:1x 500GB system drive on ATA IDE4x 1TB SATA drives in software RAIDLinux = Fedora 13So here's what happened. I set up the system to send me an email every time the mdadm stat file changed, so it would send me emails when in periodically ran a self-test. I was away and noticed that the self-test was going incredibly slow (usually took 8 hours...was on course for taking 250 days!) A colleague decided to just reboot the system.Afterwards, the system would not boot and, while all 5 drives were connected, would stop at an endlessly scrolling error message of: Code: ata4.01: exception Emask 0x0 SErr 0x0 action 0x0
ata4.01: BMDMA stay 0x64

I want to develop a bash or Perl script that will evaluate files in the local directory and delete every file that is older than a specified time period, such as three months.I write documents and save the latest modifications by putting the current date in the filename, so I can easily see which versions are the newest. I would like to clean up my directory every once in a while, though, by eliminating the copies that are more than a few months old.

I have used cp -rl to copy a folder. When measuring the size of the source and of the result of the copy du -sl returns slightly different sizes, even though diff confirms that their content are identical.Both folders reside on the same hard drive, no modifications to any of them have been done between the copy and the measure. I found nothing in the documentation of du and cp which could explain the difference.

I was messing around with the alternate character panel app and made a custom character set. I then wanted to put it on a new panel and created a new panel. I moved the character set to that panel, and then started to mess around with the panel settings (auto hide, show hide buttons, and expand, to be specific.) So far so good, until I moved the panel from the right side of the screen to the top. I already had a panel here, and it seemed not to like hiding a panel when there was already one on the top.
When the new panel hid itself, all my panels stopped responding (any clicks on them did nothing) and my processor started going at 100%. I tried a reboot and the only thing that changed is that now I can't even see my panels. I'm guessing I need to change the settings back manually through the prompt, but I don't know how to do that. I am using 10.04 and have not upgraded gnome since upgrading to 10.04.
