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

Jun 6, 2015How can we do a file replacing string on debian/rules file using sed and bash variable ? I don't seem to be able to do so. I have tried below under the install section with arch dependent amd64, as far as I know all the bash commands are allowed to be executed in debian/rules file.
I have tried this :
Code: Select all
debian/rules file
ipaddr=`<long command to find ipaddr>`
myVar=`hostname`
sed -i -e 's/somestring/'$myVar'/g' $(configs)*
sed -i -e "s/somestring/$myVar/g" $(configs)*

Nothing works. Sed works but the hostname replacement doesn't work.

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:
#include<stdlib.h>
typedef struct node * bond;
extern int jk;
and temp2.c is
Code:
#include<stdio.h>
#include<temp1.h>
struct node {
int data;
[code]...
I had declared jk in temp1.h as an extern int so why can I not initialize it in temp2.c?

Feb 25, 2010I am like almost everyone, watching videos on ..... and I am having problems with flash. When I put a video on - even if high definition or not I still get a studder from flash. The video plays but it keeps chopping up and you can see on some frames how the next frame moves on the bottom of the screen and the previous frame is still stuck on the top. Flash does not run smoothly at all - that is on every video. I am suppose to be on the latest flash version for linux off of addobe.
