Most all of this works when I execute it manually, but I cannot figure out how to get a bash script to execute it automatically.In this particular case, I am trying to build the xorg utilities. If I manually step through the process, prepending the commands with CFLAGS, LDFLAGS, etc, all of the packages build.So I created a bash script, test.sh:
Code:
#!/bin/bash
export INITFS=/initfs
[code]...
I've been googling and reading up on how to set build optimizations for my system, and after consulting the Arch Wiki, old threads here, and some mailing lists, I've concluded that the way to set CFLAGS, etc. is by putting this in /etc/profile:
Code:
export CHOST="x86_64-unknown-linux-gnu"
export CFLAGS="-march=native -O2 -pipe"

I have a bash script that changes the iptables.Now i call this bash script in my php code.When this bash script is running the part of code that contains iptables instruction is not running because we need to be in superuser mode(root)

View 1 Replies View RelatedHow can I iterate over all the files in the current directory to check for certain permissions? This is what I have:
Code: #!/bin/bash
for file in *.tar.gz
do if [ -r "$file" ]
then echo "$file is readable"
else echo "$file is NOT readable"
fi done
But this only checks that the current user has read permissions for each file. I want to check that the group "others" has read permissions for each file. How can I do this? Is there a built in function to check if a file has read permissions for the "others" group? Otherwise, I thought I might be able to use this:
Code: $ stat --format=%a file
744 And parse the output "744" and make sure the 3rd number is between 4 and 7 (since the octals 4-7 have read permissions for others).
I am having some weird problems with calling commands stored in a variable (I need to do this to assemble a command with a bunch of parameters automatically and then execute it).Example code that will replicate the weirdness:
$ echo "hello world" > "test file.txt"
$ cat "test file.txt"
hello world
[code]....
I would expect the output to be:
hello world
What happens to the quotes? I have tried various combinations of single quotes, escaped quotes, etc, but it seems like quotes in a variable are not evaluated as quotes when that variable is executed.
I'm trying to call a specific variable based on a user selection. For example:
Code: Select a file:
[1] foo.tar
[2] bar.tar
Enter a selection: I have already coded each possible selection to have its own variable. If the user selects 2 I need to select $SELECTED_TAR2, or if they select 1 I need to select $SELECTED_TAR1 and then do something like this behind the scenes:
Code: cp /home/user/$SELECTED_TAR2 /home/user/backup/$SELECTED_TAR2
I was thinking something like this:
Code: echo "Enter a selection: "
read -e SELECTED_NUMBER
cp /home/user/$SELECTED_TAR$SELECTED_NUMBER /home/user/backup

I am setting up a cron job, where i am calling a shell script to make few builds. I got struck at a point, need some expert inputs to proceed further. The script is categorized in 5 parts and in the last part while building software it asks for few questions like:-
1. Build mode choice
2. normal build
3. Copy Images
4. Arch
User manually has to input ans for these questions:-
1
yes
n
64
The ans's are fixed and this won't change. How shall i hard-code them or do something in the script so as when script flow reaches to this point it automatically take's these value. So far the cron job is not getting completed as it's waiting for user to key in these values manually. I had faced similar issue while building kernel modules but there it was easier as i had to take default values always:-
I feel like there should be a cleaner way of doing this. I have one file, for example "a.cpp", calling a function from another file, "b.cpp". Currently I have it set up so that header for "b", "b.h", has the declaration of its functions. And then I'm just including "b.h" in "a.cpp". Do I have to include the "b" header file in "a" to be able to call a function from "b"? Or is there a better way I could be doing this? Like doing something different at compile?
View 7 Replies View RelatedI have written FORTRAN code to calculate density profile. This code will open two files ( topology and x,y,z trajectory). The trajectory file contains XYZ data coordinates for multiple frames (about 20 or 100 frames for instance). One frame contains 20736 data.
Previously this code was written to open ONLY one input XYZ data file and do the calculation and would dump the results in separate file and it was running without problem. Recently my data file get bigger in size, so I decided to break the single XYZ data file into few small parts.
Now I have modified the code so that it calls the parts of the XYZ data files ( eg: maltoTHERMO_10Frames.traj, maltoTHERMO_20Frames.traj,... and so on) and do the calculation and dump the results in the same result output file. I have tested this code just with openning the XYZ coordinates and printing into another file to see wheather it collecting the data sequently and it was working fine.
This code supposedly read the x coordinate data and calculate distance and put a count accoding the criteria in the approperiate bins. But when I let the code to do the calculation it stop and shows error. (I have indicated as !** in the code). If I enable this line, it shows error but if I disable this line, than the code do collect only the XYZ coordinates.
The code is as below:
Code:
module all_parameter
integer,parameter :: MAXATOM=20736!CHANGE
integer,parameter :: midwater=1500
integer,parameter :: TOTALFRAMES=20

View 1 Replies View RelatedI built my slackware system from source code. Bootstrapped, toolchained etc.. The only thing I didn't change was the chost thinking that life would be easier if left alone @ i486. Would I have gained anything if I had used i786 or even pentium4 (pentium4-slackware-linux-gnu)?
I already got all the benefits of optimization when I used (still using) my own CFLAGS CXXFLAGS right? So changing the chost won't do anything speed wise will it? If I used march=prescott when compiling everything am I ok to just forget about the chost value? It's not gonna change anything will it?
I need to modify fs/open.c and fs/read_write.c to make my modifications. I cannot find any options in 'make menuconfig' to make these files modules rather than compiled elements. I'm thinking these cannot be modules because the file system won't work without open.c and read_write.c. Is this correct - I cannot compile fs/open.c and fs/read_write.c as modules, only as compiled elements? Or, is there some way for a module to overwrite these routines when the module is installed and re-enable the routines when the module is removed?
View 3 Replies View RelatedUntil now i haven't had to dabble with bash scripts.
I have a program that reads in data files. These are named datafile01_R, datafile01_G, datafile01_B, they then increment, so datafile02_R etc i have about 600 of these. the program reads in 3 data sets at a time from each run, so files_01 r, g, and b.
The program then does its magic, and outputs about 40 different files, depending on the file, they gone to folders named R, G, B, psa, or tracking.
The program itself has configuration files to say where the files should gone when analyzed, there is also the config files that reads in the data sets.
At the moment i have to run one set of data, then go in and manually change the input file location, and run again. But, doing this, even though a different data set, the new set overwrites the old set in one of the output folders. So i need a way to increment the output filenames after they are written and before the program is run again with the new data set.
bash: how do you make the construct ${var%% *} work? I am trying to select the first word from a variable which contains many space-separated words. I am running Ubuntu 10.10 with GNU bash, version 4.1.5(1)-release (x86_64-pc-linux-gnu) and when I try to use this construct, the expression returns the complete variable with no removal of trailing anything.

I have OpenSuSE 11.2, and I am learning Bash scripting. I was wondering how I would make a bash program, That I could have it check multiple craigslist sites [western mass, worcester mass, etc], e.g. in the Free category, and/or enter keywords, and have it update every 5 minutes, and then post the results somewhere, to a file, or even upload it to a server, or if it's even possible? (Kind of like the program "Ad Notifier for Craigslist") Would I have to do this in C/C++? If it has to be done in C/C++ It would have to be windows compatible preferably.
