General :: Arch Usability - Pass Arguments From A Shell Script To A Program?
May 7, 2010
1. What file do i have to edit in order to include /usr/local/bin in the class path (ie. I put an executable in /usr/local/bin and when I try to execute it, it says the command cannot be found, etc.) EDIT: Solved, just didn't set PATH correctly. EDIT: New problem. When I try to execute a program in /usr/local/bin, it says "fopen: john.ini: File not found" Yet when i cd to /usr/local/bin, it doesn't say that. What would cause this?
2. Once I get my system setup the way i like it, how would i go about making it into a bootable CD/DVD?
3. How would I pass arguments from a shell script to a program?
My hosting server does not allow exec() or system() calls, for security reasons. I can call a cgi process in two ways. From a .shtml page, i can issue a directive like code...
processArgs $* If I call this script with Code: ./script first second third it'll print each of the argument on a new line - exactly what I would expect. However if I call it with
Code: ./script "Single Argument" "Second-Argument" it splits the first argument in two using the space as a delimitor. The problem appears to be the call to processArgs, where $* doesn't honour the quotes around the variables sent to the script.
I've written myself a linux program "program" that does something with a regular expression. I want to call the program in the bash shell and pass that regular expression as a command line argument to the program(there are also other command line arguments). A typical regular expression looks like "[abc]_[x|y]".Unfortunately the characters [, ], and | are special characters in bash. Thus, calling "program [abc]_[x|y] anotheragument" doesn't work. Is there a way to pass the expression by using some sort of escape characters or quotation marks etc.?
(Calling program "[abc]_[x|y] anotheragument" isn't working either, because it interprets the two arguments as one.)

I am calling script 2 from script 1. Is it possible for me to pass the output from script 2 to script 1 as the value of a variable. for eg.. path=`/XXX/XXX/script2.sh`
I need to pass a large number of arguments to a function which takes variable number of arguments, such as gtk_list_store_new. But it doesn't look nice if i write something like gtk_list_store_new(NUM,TYPE_A,TYPE_B,TYPE_C,...,TYPE_OMEGA); because of large number of arguments. And, it will be a trouble to change number of columns because of need to manually change arguments to large number of such functions. So, how can i pass all the arguments to a function using a loop? Something like
The script receives multiple files as parameters and it is supposed to count the number of lines in each of them and write that number in another file.
This is my script:
Code:
while [ -n "$1" ] do lines=`cat $1 | wc -l` echo "The number of lines in file $1 is $lines." >> lines.txt shift done
Is there any other way to do the same thing, without using shift?
I wrote a C++ program that uses two different parsers. The first parser is reading program arguments from command line:./mybin arg1 arg2 ...then during program execution there's an interactive prompt asking for more parameters:
... >> (second bunch of arguments here) ...
I'd like to run my program inside a bash script, but I don't know how to give the second level arguments.
I'm using gdb to debug my program. My program requires arguments (e.g., ./prog -dfile).But if I use gdb as in gdb ./prog -dfile, gdb wants to interpret the -d argument. How do I pass an argument to my program via gdb?
I am calling a URL from shell script and passing few argumants,Here i have to pass file content as one argument.How can i pass file content through URL.
eg: content=`cat /Users/test1.txt` open http://localhost:8080?filecontent=$content
I am new to bash scripting (not programming in general).
I am writing a bash script that will run a Python script I have written.
I want to be able to do the following:
Pass parameters to the bash script via the cronjob (so I can have two cron jobs) one to be run with parameter 'foobar', and the other 'foo' switch based on the parameter passed to the bash script (by switching, I mean an if/else based on the paramter passed to the bash script).
I have a Python script that I run which needs to execute under a special environment, so I would run the program like so from my working directory (~/project/src):
python manage.py shell
This opens up an interactive shell for me to start typing my own commands.I have another set of administrative activities that I would like to house in another directory (~/project/admin). The manage.py is really finicky about running from the working directory. So, to make this whole thing work, I made a script which starts off like so:
#!/usr/bin/python ../src/manage.py shell
There are a couple problems with this. The first is that it doesn't work:
/usr/bin/python: can't open file '"/../src/manage.py" shell': [Errno 2] No such file or directory
How do you specify multiple parameters to the interpreter?How do I change the working directory?
I have a linux system connected to an external sensor device that spits out strings of serial data every few seconds. I need to send the data to a remote URL for logging and graphing purposes.
The data coming down the serial is essentially in the format:
And I need to call a URL from my linus box in the format
wget -s [url]
I can read the data to the shell using cat </dev/ttyS0 but I'm now stuck as to how I might then format that data and pass it to a shell script which would presumably run in an endless loop and contain the wget.
(For function arguments): Scalar arguments are passed by value, which means that a copy of the argument is made for processing in the function, and changes to the argument in the function won't be reflected back to the calling program. Objects though, are passed by reference: any changes to them in the function are reflected in the calling program. What sense does this make? Why have they done this?
from this multirow taskbar, extensible quicklaunch, clock day date are only important. And i want to doubleclick upper left corner of a window as alternative close. A better variant is to use the third wheel button on a mouse - to close any window just by pressing wheel inside a window (similar to Firefox close a tab, or in qip close a tab..)
I have some messy code that I wrote a while back and I am trying to organize it. The program opens xpaint and uses xwit and xte to draw packman and so on. I want to split it all up I am going to add more to it. Basically like i would want drawing packman in one function i guess you could call it and then coloring him or the background in another
#xwit -id $paintersMom -focus -raise #sleep 1 #xwit -id $paintersMom -warp 30 390 #// fill in command on tool bar #sleep 1 #xte 'mouseclick 1' #sleep 1 #xwit -id $canvasWin -warp 221 40 #// color selection #sleep 1 #xte 'mouseclick 1' #sleep 1 #xwit -id $canvasWin -warp "$(($X-150))" "$Y" #//location on pac man #sleep 1 #xte 'mouseclick 1' #sleep 1
#xwit -id $canvasWin -warp 62 44 #// selecting color black #sleep 1 #xte 'mouseclick 1' #sleep 1 #xwit -root -warp 62 120 #// selecting back to canvas #sleep 1 #xte 'mouseclick 1' #// color canvas black #sleep 1 #xwit -id $paintersMom -focus -raise #xwit -id $paintersMom -warp 27 108 #//click back to pencil #sleep 1 #xte 'mouseclick 1' #sleep 1 </code>
Here for example $paintersmom is would be in the drawing of pacman but I would also want to use it when I colored him in.. but I would want both processes in a different shell script.
I'm using Ubuntu 10.04 and I have a 1TB NTFS (internal) hard drive where I put all my files. The drive shows up in the "Places" menu, and if I select & open it, the drive and all the scripts & text files in it work. But, if I go to run the scripts without opening the dive in the places menu first, it just gives an error.
1. What is being done when I select the drive in the places menu?
2. Can this be set up automatically, so I don't have to open the drive every time after I start up?
I want to have a choice or more preferable pass shell as command line argument when I ssh to an linux account.i.e. If John logs in to account "zzz" on server "abc", by default definition of account "zzz" n server "abc" he get csh.But Sally desires that when she logs in to account "zzz" on server "abc", she needs the login shell to be ksh,and Rick wants bash when he logs in to account "zzz" on server "abc".What is the most non-intrusive / easiest way to achieve this? Each user can set their preference on ssh command line or create a simple alias by each shell, but not sure how to do this.
If I pass to my shell environment as a regular user will it apply to builds ran under sudo?I posted a thread similar to this regarding a build with TOR; however, this is applicable to all programs.
