Programming :: Gawk - Using Variable In Search Pattern?
Apr 4, 2010yes, this is a homework question, but no - I'm not trying to get anyone to do it for me. I think that I am really close, but can't quite get one small aspect to work. in gawk, I want to include a variable name in the search string, but the below code doesn't work.

Programming :: File Renaming Based On A Pattern Match
Jan 8, 2011What I am attempting to do is rename some television shows into the format that my PVR will understand for the naming convention. I have a script that cleans them up about 95%, now I just cant figure out the last little detail..
For example: NCIS_01.mkv
I think it can be done in sed, but I just figure out how. I need it to be renamed to: NCIS_s01e01.mkv
How can I make sed (or something else) match the last "_" and any numbers after it until the period and then insert text between them reliably?
Depending on the show, it can be something like: This_show_name_243.avi so I need it to be more flexible than I can figure out how to do..

Programming :: Bash - Calling A Specific Variable Based On User Input?
May 3, 2011I'm trying to call a specific variable based on a user selection. For example:
Code: Select a file:
[1] foo.tar
[2] bar.tar
Enter a selection: I have already coded each possible selection to have its own variable. If the user selects 2 I need to select $SELECTED_TAR2, or if they select 1 I need to select $SELECTED_TAR1 and then do something like this behind the scenes:
Code: cp /home/user/$SELECTED_TAR2 /home/user/backup/$SELECTED_TAR2
I was thinking something like this:
Code: echo "Enter a selection: "
read -e SELECTED_NUMBER
cp /home/user/$SELECTED_TAR$SELECTED_NUMBER /home/user/backup

View 1 Replies View RelatedProgramming :: If Statement Pattern Search / End Of Pattern Special Character?
Apr 29, 2010I have to enhance the behaviour of a backup script written in perl. I don't need to change it, what I need to do is to create a bash script that does some checks like file name and file size, execute the backup script then check if the backup files match the original files.Here's how I try to do it:
- read the files from the original files folder
- store them in an array
- search in the array the files that have a specific file extension
- store the file names that match the search pattern (I know the backup script skips some files so I can hardcode the search pattern)
- run the backup script
- read the files from the backup folder
- store them in an array
- compare the original files name and size stored in an array with those from the backup folder
- send a report email
General :: Add (not Replacing) A Pattern Match With A Similar Pattern?
Aug 30, 2009I'm writing a bash script to search html files, and when I find any occurrence of an img src tag like this:
<img src="123-picture-normal.jpg" alt="some random user entered text" border="0">
I want to add a second line below it that looks like:
<img src="123-picture-thumbnail.jpg" alt="some random user entered text" border="0">
All I need to do is duplicate the line but replace "normal" with "thumbnail"
Each file can have multiple img src tags with different numbered jpgs.
I have a feeling this is a job for sed, but I'm struggling with it. Any ideas?
General :: Find Pattern After Specific Pattern
Oct 11, 2010I want to go through a log file and find pattern1 and then a pattern2 only after pattern 1.So for example I want to know howManyRecords was in 13:30.I figured I grep for "start time for the job" and then only after that (and before the next occurence of that) grep for "howManyRecords". Is this a sane way?

Programming :: Bash - Read Content Of File To Variable And Use This Variable In For Loop ?

For example:

Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).

View 1 Replies View RelatedUbuntu :: Kill Window Based On Based On Title Instead Of PID?
Apr 24, 2010I am working on a set up, and I like to be able to toggle compiz on and off, or toggle dualscreen on and off. The thing is, I also have conky on my desktop as well as a terminal window embedded in my desktop (that requires compiz). So, when I turn comiz off, or resize my desktop, I want to be able to reposition conky/embedded-terminal and the terminals position is relative to my conky position and the size of my virtual desktop.
I can do this all fine, except that to reposition the terminal I need to kill it then reopen it. But if I kill gnome-terminal it kills ALL gnome-terminals instead of just my embedded one. How can I specifically close my embedded one and leave any others untouched? Lets say that the title of my embedded terminal is "trans777"Also, the trans777 titled gnome-terminal will be killed when compiz is not running.

OpenSUSE :: LAMP Pattern Not Installing Anything?
Dec 23, 2010When I try to install the pattern "lamp_server" with zypper on a fresh openSUSE 11.3 box I'm only getting the metapackage "patterns-openSUSE-lamp_server" installed, nothing else.Apache, MySQL, and PHP are all listed as "recommended" only.I know how to install the packages individually, and I know I can force matters with the "--recommended" flag. Unfortunately installing the recommended packages also wants to throw in apparmor and sw_management, neither of which I want right now.Am I overlooking something? The command I used:zypper install -t pattern lamp_serverMy main goal is to communicate this process to others, so I'd like to give them the option of the simpler pattern install.
