I have a script that creates a textfile with ip addresses and ports, but the ports are in hex format so they need to be converted.
Currently I have this code:
Code:
I'd like to have the second column in decimal instead of hex, like this:
Code:
Is there any way to do that with awk, preferably in a oneliner? Would printf be an option?
I have a script in the works that reads an MP3 file and gets the track length. Trouble is, it gives me the total seconds, like this:
Sample Track.mp3 = 225.55 seconds
What I'd like to have is that 225.55 converted into minutes:seconds format (in this case, 3:45). How can I do this?
snappy title to grab attention. maybe not stupid, but bleeding difficult to use, talk about a non-obvious, non-intuitive interface; I want to enter a hex value, and have the calculator convert that to decimal. So, I use the pull-down, choose 'hexadecimal', enter the hex value, then change the pull down to 'decimal', expecting to see the decimal (base 10) value. What do I see? The display just adds the hexadecimal base to the end of the hex value I just wrote! Where's my decimal (base 10) number damn it? I can't for the life of me work it out.

View 3 Replies View RelatedI'm writing an if statement where a variable is a number such as 14.05 (this is actually a temperature) and I want to compare it to a predefined value, sample code below:
Code:
I have all sorts of errors regardless of how I do this (double quotes, square brackets). The best idea I've had is stripping off the decimal place so it's a 4 digit number (e.g warning=1503 and DEV_TMP=1405) however this seems a little unnescessary and I'm sure there's an easier way of achieving the same thing.
Around 2008 i seem to remember PartEd on the command-line was able to rescue deleted partitions and gave a choice of whether to recover the partition as a Primary or Logical Partition. I have tried testdisk but didn't really grok what i was doing. I successfully moved a "Windows Recovery" partition to the end of my hard-drive, immediately after the drive's Extended Partition.

View 7 Replies View RelatedBasically I have a dir that contains my makefile and another directory inside this called source this holds main source files. External to these I have a couple of dirs common and drives.
In my make file I use
To include the protoypes from the headers in the folders common and drivers used by source, this works fine. However in common and drivers I use a few variables that are set in the source dir. I set these with externs inside the common and driver files. However I'm sure I should be able to set the directory path for source inside my makefile. So say I have inside source hardware.h with prototypes, I set DINCDIR = -I/Source -I../Drivers -I../CommonFiles
Then from a c file inside my common folder I say #include "hardware.h" the file should be able to see hardware.h and it's protoypes. However I get:
Is there some way I can get the extern dirs to see the source dir?

What I want to ask is, if the first program crashes at Checkpoint A, then B will never gets to continue, then normally how do programmers avoid this kind of deadlock due to crashes inside the critical section?
What I want to do is from a file having block like
<event>
8 3 0.2685416E-02
2 -1 0
21 -1 0
[code]...
The first line after the "<event>" is its process-id, so I would like to have at the end a summary of how many "event" block I have for each type, ie how many
6 1 0.2685416E-02
or how many
7 2 0.2685416E-02
etc etc
I do not know in advance how many different-kind of block I will have, so it has to be a bit smart to scan the file, and make an new "summary" info for each unique type I was using something like
awk '/<event>/,/</event>/{if ($3 -eq 0.2685416E-02 ) { print $1" "$2" "$3}}' file > out
and then
grep -c "$1" "$2" "$3" but with no success since my awk commands prints all lines of each block
Suppose, that in advance I do know the $3, ie the 0.2685416E-02 which is a kind of weight
