General :: Pass Parameters To A Shell Script Running As Cronjob?

Dec 7, 2010

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).

General :: Shell Script File - Pass Multiple Parameters To Interpreter?

Feb 2, 2011

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 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 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/ shell

There are a couple problems with this. The first is that it doesn't work:

/usr/bin/python: can't open file '"/../src/" shell': [Errno 2] No such file or directory

How do you specify multiple parameters to the interpreter?How do I change the working directory?

Ubuntu :: Pass Parameters To Bash Through Shellscript?

Mar 21, 2010

How 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?

Ubuntu :: Pass Parameters To Grub At Boot Time?

May 2, 2010

Old Toshiba laptop model A30 -- tried various installs 8.04/9.04/9.10. They all hung trying to boot the install disks after the initial few screens. Finally, I got 9.10 to install, dual booting XP and 9.10 by choosing F6 from the initial menu, and putting an X beside:


and then hitting escape.But, after the install, I couldn't boot 9.10 from grub as it hangs after about 30 seconds of trying. The live CD would not work without the above parameters being set as described above, but does work with them set! I need those same parameters passed to grub at 9.10 boot time, but I can't figure out how to do that. I've had many successful installs of Ubuntu across a number of desktops and laptops, but I never had to deal with the guts of grub before. It all just worked.

General :: Which Parameters Can Be Used To Shutdown A Computer Running OSX In 30 Seconds

May 12, 2011

Simple question: what parameters can be used to shutdown a computer running Linux/OSX in 30 seconds? I've always run Windows, where I would go shutdown -s -t 30 but the parameters are different. I've looked it up here but it will only let you shut a computer down at a specific time (like 8:00) rather than in a specific amount of seconds.

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?

Debian Multimedia :: Cronjob No Longer Running

Aug 4, 2015

I am running Debian 8 with the Xfce Desktop Environment.

A few weeks ago I created a cronjob which randomly changed my desktop wallpaper every two minutes. Here is that cronjob:

Code: Select all*/2 * * * * DISPLAY=:0 /home/alessandro/bin/random_wallpaper

Today, however, this cronjob stopped working. (The random_wallpaper script still works as intended.) The only changes I made to my system were

1) I modified my compton configuration settings; and
2) I installed a new display manager, SLiM.

I'm not sure why any of these changes would prevent my cronjob from running though.

Programming :: Access Grub Parameters Using Shell Scripts?

Apr 12, 2010

I am setting up my test / development machine with the following scenario in mind : I boot the machine and then select one of a number ( e.g. 3 ) boot options in Grub ( Normally "OpenSuse", "Safe Mode" etc., but in this case "System Restore Dev.", "System Restore Test" ). The only difference between these options are the settings ( e.g. "vga=378" ) in these cases something like "distro=dev" / "distro=test".

In a script run on the booted system I can extract the value of the "distro" parameter ( in this case "test" ) and use it as input for a command line tool. Meaning that name entered as the value for the "distro" parameter is used for loading a file when the system is up and running. The command line tool then restores the partition with the contents of the file and reboots the system.Now, my problem is this : How to I access the Grub arguments? Code snippets ( in shell scripting or python preferbly ) are more than welcome.

Ubuntu :: Korn Shell: Syntax Error On Test A Function With Parameters?

Jan 4, 2011

Some may recall I recently gave up on bash, rather than give up my programming style.Surely I will have reason to return but that's another story. My little issue now:I am debugging a new [Korn] shell script. I have a function that performs a specialized match on a string and I see that I am able to call that function with no problem, with both of it parameters. The function does not do any print or echo command - it uses "return" for a TRUE (0) of FALSE (1), as is the shell exit code convention. Thus, I have the following test:

if [[ match_except_release ${PATH_DIR[$LC]} bin ]]

Programming :: Pass Variable From One Shell Script Into Another

Oct 2, 2009

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

pkill xpaint
res=`xwininfo -root | grep geom | sed -e 's/^.*try ([0-9][0-9]*x[0-9][0-9]*)+.*$/1/'`
Xoriginal=`echo $res | cut -d 'x' -f 1`
Yoriginal=`echo $res | cut -d 'x' -f 2`

X=`echo "($Xoriginal/2)-400" | bc `
Y=`echo "$Yoriginal/2" | bc `
bob=`echo "$Y/2" |bc `
echo $X
echo $Y

/usr/bin/xpaint -size "$Xoriginal"x"$Yoriginal" -popped &
sleep 4
paintersMom=`xwit -all -print | grep XP | cut -d ":" -f 1`
canvasWin=`xwit -all -print | grep Untitled | cut -d ":" -f 1`
#toolres=`xwininfo -id $paintersmom | grep geom | sed -e 's/^.*try ([0-9][0-9]*x[0-9][0-9]*)+.*$/1/'`
#canres=`xwininfo -id $canvasWin | grep geom | sed -e 's/^.*try ([0-9][0-9]*x[0-9][0-9]*)+.*$/1/'`

#echo $paintersMom
xwit -id $paintersMom -move 0 0
xwit -id $canvasWin -move 0 0
xwit -root -warp "$X" "$Y"
sleep 4
for((i=45; i < 315; i++))
xte 'mousedown 1'
ang=`./deg2rad $i`

movex=`echo "$X+$bob*c($ang)" | bc -l`
movey=`echo "$Y+$bob*s($ang)" | bc -l`
xwit -root -warp "$movex" "$movey"
xwit -root -warp "$X" "$Y"
xte 'mouseup 1'

#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

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.

CentOS 5 :: Pass Shell As Command Line Argument When I Ssh To An Account

Jan 25, 2011

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.

General :: Running An ASP Page From A Shell Script?

Jun 18, 2011

I am trying to access an aspx page which, when accessed with certain parameters in the URL, downloads a file. I need to do this with a shell script, rather than interactively. I tried using wget, but I get a response of 302 from the server, which redirects me to the default page and then downloads the default page html itself. I quickly tried curl which seemed to be doing the same thing. It works perfectly from browsers on either Linux or Windows. Originally, I had a problem with interpretation of ampersands in the URL, but I put quotation marks around the URL, so that isn't the problem now.

I cannot fix this on the server side, because the aspx page will be accessed on a variety of servers which are probably all set differently and which aren't under our control.

General :: Running Shell Scripts With Cron

Sep 24, 2009

I've been having a bit of trouble running a shell script with cron. A friend of mine does a community radio show and the station has a live stream but no podcasts, so I've set up a script to record the stream and encode it as an mp3 while I'm away using mplayer and lame -that's what I'm trying to do anyway.

Here's the script, but it doesn't seem to run- at least, I don't see any of the files it should be outputing, would they be in the cron.weekly directory (where I have the script) or in my home directory?

#This is a script to record 'The Unnamed Show'

#it will record the show from the live stream, then convert the output #to an MP3

#Finally, it will delete any files no longer required HOME=/home/byron/

Ubuntu :: Running "at" Command Within A Cronjob ?

Mar 3, 2011

I ran into a problem when wanting to execute the "at" command from within a cron job.

Essentially, I have a daily crontab job that is launched at "the wrong time" (middle of night). I want to delay the execution of an import script until around 07:00. Editing the crontab is not an option (shared environment).

So I figured: Use the "at" command from within my script that is triggered (indirectly) by crontab: Code: #!/bin/bash at -f ./ -v 07:00 I know my script is started with `pwd` pointing at that same directory.

Running the "at" command directly from terminal works.

Running the script file above from terminal works.

But... when triggered from within crontab it does not work. I get exit code "1" from "at".

I searched man pages for "at" without much success. No mention of meaning of exit codes.

How to locate the sources of the "at" command.
