General :: Awk Gsub() Command - String (column) Manipulation - Replace The Value Of The $1 Column In The Awk Print String?

Mar 7, 2010

i use this script to get the time and date of back and fourth transactions for a particular execution id. I use a substr command on the 5th column to to cut the milli seconds off the time value. - otherwise the times would look like 08:30:04.235

grep <executionID> <auditfile> | awk '{ print $1, $2, $3, $4, substr($5,1,8}
FIX -> Mon 3/1/2010 08:30:04
FIX <- Mon 3/1/2010 08:32:36
FIX <- Mon 3/1/2010 08:35:08

[code].....

anyhow - i append two sed commands to further clarify the direction of the message.

awk '{ print $1, $2, $3, $4, substr($5,1,8} | sed -e 's/->/ ->IN/g' | sed -e 's/<-/<-OUT/g'
FIX -> IN Mon 3/1/2010 08:30:04
FIX <- OUT Mon 3/1/2010 08:32:36

[code]....

I tried using an awk gsub () command within the string instead of the two seds, but it did not work:

awk '{ print gsub(/<regex>/, <replace with>,$1), $2, $3, $4, substr($5,1,8}

the sed works ok, but it would be cooler to make the replacement within the awk command:

gsub(/->/,-> IN, $1)

Is there a way where i could replace the value of the $1 column in the awk print string?

Software :: Combine And Partially Overwrite Text Files?

May 18, 2010

I need to overwrite the first say 50 or so lines of an xml file on an everyday basis. The first 50 lines of the file are always the same and the 50 lines they get replaced with are always the same. Is there a way to create a file with the 50 new lines and somehow copy/merge/overwrite the larger file such that the 50 original lines would be replaced but the remainder of the file would be untouched?This seems simple, there has to be a way to do it. I'm just not smart enough to figure it out.

Slackware :: Use The Ls Command To List Files In One Column?

Sep 20, 2010

I am doing a spreadsheet for work (for importing data into a new database) and I have hundreds of image files which need to have just their file names in one column called Product Code. Is it possible to use the ls command to list the contents of a directory in one single column so that I can copy and paste to the spread sheet?

Also, is there a single command to remove the file extentions for a batch of files? Bulk rename is what I need, I guess but just to remove the file extension (.jpg on all of them). The normal use of ls lists them in multiple column form and when I copy and paste those it will not let me copy just one cloumn at a time. The spreadsheet only has three columns:

New Product Code Old Product Code Pictures New Product Code will be left black, and the Old Product Code is just the image names. The picture column will be the patch-to-the-image for each image. I am not sure that is even possible in a spreadsheet.

General :: Removing Specific Field Seperator To Combine Two Fields?

Dec 2, 2010

I am trying to remove the space between the 2nd and 3rd fields but just cannot work out how to do it. I've considered sed, cut, awk...I know with sed you can replace all instances within a file but can you also specify to remove, say, the 2nd instance of a space in each line (this would be perfect for me)?

General :: Adjust And Combine Multiple Lower Quality Photos Into One Better Using FOSS?

Mar 12, 2011

I have multiple noisy photos (caputed without tripod) that needs to be adjusted (moved/rotated) and averaged.

How it's better to do it in Linux with FOSS console-based programs?

Current way is something like:

mplayer mf://*.JPG -vo yuv4mpeg:file=qqq.yuv
transcode -i qqq.yuv -y null -J stabilize=maxshift=500:fieldsize=100:fieldnum=6:stepsize=50:shakiness=10
transcode -i qqq.yuv -J transform=smoothing=100000:sharpen=0:optzoom=0 -y raw -o www.yuv

Update: Experimented with "Hugin". It only distorted all photos according some "projection" and refused to merge them: enblend: excessive overlap detected; remove one of the images. Of course "excessive" - they're all almost in the same place. No averaging? /* and images are not actually aligned */.

Proceeding to experiments with enblend/panorama_tools/ale.

Ubuntu Multimedia :: 10.04 - Any Way To Sort Rhythmbox By Album (Year Wise)

Feb 3, 2011

I just migrated to Ubuntu 10.04 from windows and I could not be more satisfied, except for one minor, nitpicky detail. In iTunes I was able to sort my music by "album by year". That is, my music was sorted primarily by artist, then by album year. So each artist had their albums listed in chronological order. My library is meticulously tagged, so every track on every album is tagged with the same YEAR value. Is this possible in Rhythmbox? Is there a plugin or will i have to edit a .conf file (or similar) somewhere? I'm new to Ubuntu, but not afraid of getting my hands a bit dirty, so to speak.

General :: Insert Column With Awk / Sed Between Two?

Jan 18, 2011

I have a two column file and I need to create a new column in between the first and second but the new column adds a value to the first. E.g.code...

I thought I had figured out how to do it with the following but it just hangs:

awk -F '{print $0,$0+25,$1}' file_in > file_out

Also tried the following to no avail:

awk -F,-v OFS,'{print $0,$0+25,$1}' file_in > file_out

I can add the new column with the added value to the last column easy ( awk '{print $0,$0+25}' file_in > file_out).

OpenSUSE Install :: Set System-Wise Environment Variables ?

Sep 9, 2010

I just recently reinstalled openSUSE 11.3 last night with the GNOME desktop. Since I'm starting fresh again, I'd like to set up my System as flawless as possible.

So, my question is stated in the Title. How do you set System-Wide environment variables on OpenSUSE 11.3 // GNOME? I usually set them by adding an export to my ~/.bashrc, but I remember in Ubuntu that I could add them to /etc/environment. I checked that file out on my system, and it has a the default comment on it stating:

"This file is parsed by pam_env module...Syntax: simple "KEY=VAL" pairs on seperate lines"

This seems to be the spot to add my "export JAVA_HOME=/usr/java/..etc", etc. but I wanted to clarify before I went ahead and made any changes.
