I am trying to learn some script skills. I have seen such a bash shell: Code: for x do sed -f sedsrc $x > tmp.$x done then we can trigger the shell script from the command line: ./shell t1. My question is that it seems the "t1" will pass to the x in "for x"...
View 2 RepliesHow do I pass file names as parameters to the shell through a script? I have installed 'wipe' from the repos and it is a shell based app. so I made a shellscript and put it in my script folder.
the normal usage of wipe is 'wipe -q /path/to/file' so if I were to make a shell script, right click on the file in question, and run the script on it, how to I permit the shell to wipe that file only, in other words pass it as a parameter. I think on windows it was the use of %1, such as. 'wipe -q %1' for example, which was simple enough. how to I achieve this with bash?

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
<code>
#!/bin/bash
pkill xpaint
res=`xwininfo -root | grep geom | sed -e 's/^.*try ([0-9][0-9]*x[0-9][0-9]*)+.*$/1/'`

echo $X

sleep 4

for((i=45; i < 315; i++))
do

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 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 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.
View 6 Replies View RelatedIs there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:

...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.

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?
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?
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.
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.

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 would like to create some aliases for bash shell. On other Unix/Linux machines I have done this using the alias command like this: alias rm rm -i
When I type that into a terminal on Ubuntu, it looks like alias is not installed. I get this:
bash: alias: rm: not found
bash: alias: rm: not found
bash: alias: -i: not found
I tried adding the alias to .bashrc instead, but then I get the same error message every time I start terminal. Just for fun I tried apt-get install alias, just to see what would happen, and it installed something called libperl-alias instead, and alias still doesn't work.
I'm used to being able to put a script in ~/bin and having it overrule the system version of a command. However for "time" or "kill" since the bash shell implements a version of the command (i.e. /bin/ version is not used) doing this is not enough. How can I get the shell to run my own version instead of the version in the shell.I understand the implications of doing this. I know what I'm doing, I can always /bin/whatever if I want to get the old version (or just chmod -x ~/bin/whatever).
