I am working on a project that needs to use structures and I'm pretty sure string arrays. First I declare my structures and they must be exactly like this.
typedef struct
{
int hour;
[code]....
I would like to check if the 3rd character from the end of a string is a d or p using awk and the field seperator would not help for this problem, i.e.
Code:
splitting a string by every nth characters. I'm using Python 2.7.1 because I'm using older libraries, if that matters.
For example, if this is my input:
Quote:
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed ac elit nibh, vitae venenatis ligula. Vestibulum a varius turpis.
Splitting it by every 10th character should produce this list:
Quote:
[ "Lorem ipsu", "m dolor si", "t amet, co", "nsectetur ", "adipiscing", " elit. Sed", " ac elit n", "ibh, vitae", " venenatis", " ligula. V", "estibulum ", "a varius t", "urpis." ]
How can i split a string like this,
Code:
This is my first line.
This is my second line.
This is my third line.
into,
Code:
"This is my first line.", "This is my second line.", "This is my third line."
in C++.
i.e. split the code at every new line
copy string a to string b and change string b with toupper() and count the chars

Is there a way to compare an array in a while conditions?
I have one array that contains the results of some search and if the script has found all the items, then it should stop, so my idea is to have a while loop � la:
Code:
If I umount both of them, can I run an e2fsck on each at the same time through 2 putty sessions, or will that not really gain me anything from doing them one after another?

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

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

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?

View 11 Replies View RelatedMoving right along, I have a folder of MP3 files containing various Movie sound tracks and scores. I'm using Audio Tag Tool to tag all the files at once with an "Artist" of "Soundtrack", and to inherit the "Title" tag from the file name. After that, I will rename all the files (Using Audio Tag Tool -- awesome program, btw) with the format "<Artist> - <Title>.mp3"
The problem, is many of my files already contain the string "Soundtrack", which would be redundant. I happen to be a perfectionist, so I'm unable to ignore it and move on. Hence my question to you fine folk: I want to delete all instances of "soundtrack" (-i case irrelevant) in the filenames before I go through the above steps. But, its not quite that simple. This is a sample of some of the file names:

So I have a system that is about 6 years old running Redhat 7.2 that is supporting a very old app that cannot be replaced at the moment. The jbod has 7 Raid1 arrays in it, 6 of which are for database storage and another for the OS storage. We've recently run into some bad slowdowns and drive failures causing nearly a week in downtime. Apparently none of the people involved, including the so-called hardware experts could really shed any light on the matter. Out of curiosity I ran iostat one day for a while and saw numbers similar to below:
[Code]...
Some of these kinda weird me out, especially the disk utilization and the corresponding low data transfer. I'm not a disk IO expert so if there are any gurus out there willing to help explain what it is I'm seeing here. As a side note, the system is back up and running it just runs sluggish and neither the database folks nor the hardware guys can make heads or tails of it. Ive sent them the same graphs from iostat but so far no response.
I'd like to improve my computer's performance by storing files' system location (e.g.: /home/user/speech.odt) and HD position (head, sector, etc) and do the computer use that info from ram memory.I have a directory with several files and when I cd and ls it, it takes a while to the computer answer me. Plus, it would return immidiate find results.

I lastly used KDE (version 1.x ). Now I'm using KDE 3.5 for several weeks and one thing really annoys me: there are a lot of programs that don't remember their last window position and/or size. They always default to a specific location/size when I close and open them again. I give you some examples:
Program that doesn't remember anything:
- Konqueror
Program that remembers window size, but not position:
- KMail
Nice Program that remembers everything:
- Basket Note Pads
Is there a way to tell these programs to remember their position/size?And a second question about konqueror: Can I tell konqueror to remember the view mode? I prefer MultiColumn view, but it always defaults to Icon view.

I am using ubuntu. I have Cairo clock on my startup list, but after logging in cairo-clock appears on left top corner, but as it is the position reserved for computer, my home, mounted volumes etc. So I want to change default position of cairo-clock to left but there is no such option in the preferences of cairo-clock. My cairo-clock version is cairo-clock 0.3.4. Can I edit any config file of cairo-clock.
