Programming :: Make A New Folder For Each File In A Particular Folder
Mar 28, 2011I been using linux for a while, but I havent had the time to really learn it. Something Id like to get more familiar with is bash so here is a simple example of something I would like to do:
I have a directory full of files. For each file in the directory create a new subdirectory with each files name.
I tried this:
#im already in this directory
aaa=./*
for a in $aaa
do mkdir $a
done
One of the problems is that there are spaces () and - in the filenames so I get many subfolders with names like "-" which i don't want.
I tried stuff like:
aaa=./*
for a in $aaa
do mkdir "'"$a"'"
done
This of course also did not work.
Additional I tried just creating a folder with the name of one of the files and I got this:
mkdir: cannot create directory `(audio) - R56339.EXE': File exists
Well yeah a file exsists with that name, but I want to create a folder- why is there a conflict?
Just to be clear here are the contents of this folder:
~/Desktop/LAB/Media/Drivers - (Image Deployment)/Optiplex_GX260/XP> ls
(audio) - R56339.EXE (NIC-Onboard-Intel) - R54402.EXE
(Modem-datafax-V92) - R54403.EXE OEM_Applications

Programming :: Make A New Variable With The String From The Old Variable Btut Without Any Plus Sign?
Apr 7, 2010my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.
i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't
foo=+12.40
bar=${foo#+}
Programming :: Make A Folder For Each File In A Directory Then Move The File Into It
Nov 29, 2010Initially I thought - use a for loop with ls in it:
Code:
However this causes lots of problems (folders have extensions, I have duplicate folders, the names with spaces create a folder for each element of the name).
The contents of the folder is basically movies (some with subtitles). Some of the names have things like (original) or CD1 CD2 in them.

Aug 21, 2009I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.
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).

Programming :: Declaration A Variable In One File And Initializing In Another?
Nov 25, 2010I made 2 files which are different from the program above one is temp1.h and another is temp2.c to understand how extern is used. So here is temp1.h
Code:

extern int jk;
and temp2.c is
Code:
#include<stdio.h>

I had declared jk in temp1.h as an extern int so why can I not initialize it in temp2.c?

Programming :: Check That The Same File Exists Within Two Different Directories Using A Filename As A Variable?
Apr 30, 2010I am in need of a way to check that the same file exists within two different directories using a filename as a variable. Here is the process which requires it: The script is reaches out (via ftp) and pulls down a file(s) and delete it afterwards. This is halfhazard because in the instance it doesnt pull down the file, yet still deletes it, we are up a creek. I am looking to pull it down to a temp location and then verify that file exists in the location in which it needs to be present to process before deleting it, adding a little extra layer for security. The script itself is finished.If I put a file name in manually it works perfect. I just need a way to pump the filename into the variable.

Feb 25, 2011Code:
#!/bin/bash
VARR=`cat /proc/asound/cards | grep HDMI | cut -c 1-2`
VARX="defaults.ctl.card $VARR"
VARY="defaults.pcm.card $VARR"
FILE1="alsa"
FILE2="alsa.new"
echo $VARX
echo $VARY
sed "s/defaults.ctl.card*/'$VARX'/g" $FILE1 > $FILE2
This is what I have right now. Well, I thought I knew sed, and apparently I don't... I tried writing this for someone else, and this has given me trouble, so since the user pretty much figured it out on his own, here it goes.
Say VARR=1, so VARX and VARY contain the above text, appended by 1.
What I am trying to do is replace the text "defaults.ctl.card 0" by VARX and "defaults.pcm.card 0" by VARY. The contents of FILE1 is the file being used to search for both text fields, and FILE2 is the output file. I tried using single quotes, double quotes, and a mixture of both, and no go whatsoever. So my question... What is the proper way of searching for text within a file and replacing with a variable?
Programming :: Parse Multiple Variable From Text File With Bash?
Jul 13, 2010I am trying to think of a logic where my file contains some data I had to read and do some processing. Issue is that file contains data multiple times. For example:
:::::::::::
var1=value1
var2=value2
[code].....
I have to read first paragraph of variables and do some processing and then move on until the end of file. Variable names are same in whole file but for each paragraph the value is different. I can't think of a logic to attain this task. How can I do it? It should be a simple bash script, but I am not able to work out.

Programming :: Know Which File Under The Folder Is Being Opened / Created For Writing?
Apr 23, 2010My program need to monitor the foler to know which file under the folder is being opened/created for writing. I add the folder into watch list using inotify_add_watch, when a file -- say 'AA' -- is created, I'll get the event through read api call. But the inotify_event only have file name 'AA' and a event mask. these parameters can't help me to know how the 'AA' is created/openned. So I have to scan the /proc folder to get to know how is 'AA' created/openned. I don't think this is a efficient way, especially if there are lots of files are openned/created in a short time span.

I would like to explore when i run certain targets how the rules work, which files cause dependency rules to work and why. Also i would like to know ALL the targets that are available to me. i couldn't find any way to 'debug' makefiles or to put it in such debug mode that i see all the information i need when i run a certain target.
