Where the numbers are the number of processes being run by the user (the name right next to it).if I input the command egrep myFile into the terminal, it should look for every line with the letter x in myFile, right?
Are there any tools to view/edit user space memory of running processes on Linux?
It would be a great learning tool.

I'm trying to write a script that searches my files and lists them by date. Can someone point me in the right direction? I've been looking through the books that i have but i'm just not finding the right commands to search dates.
View 7 Replies View RelatedI have several directories of subtitles for some videos, but all the text for the subtitles in each file is in uppercase, and I would like to convert the files' content to lowercase, all in one go. I found on a website a bash command that would do each file separately:tr '[:upper:]' '[:lower:]' <input.txt> output.txt but of course involves specifying the input name and output name for each file.I have been trying to do it in a script that would work for all files in the current directory, without having to rename them each time, if that's possible. So far I've got the following, which doesn't work:
#!/bin/bash
for file in $@; do
tr '[:upper:]' '[:lower:]'
done
However, my web searches cannot locate a way of specifying "each file in current directory" in conjunction with the "tr" command, but also without having to rename the file once converted to lowercase. Is it possible, or would the tr command have to create a new file for each converted file?
I'm writing a script that needs to spawn 2 or more processes and wait for their return status. I have a method to do this by waiting on each process individually like this:

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.
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/
I have been playing around with shell scripting, nothing too complex just learning the basics. if i try to run a script as root (by entering "sudo" then the "command") it says command not found. i can only do it ass root if i specify the full path (/home/username/bin/command) im pretty sure the directory that my scripts are in are part of the superusers path.

I would like to do the following: Create a banner for any user logging in through ssh which warns him/her about the number of processors being used already by other users (or conversely the number of free processors). For example, if a user logged in he would then see a message like: Warning! 7 out of 8 processors are in use.I already figured out how to do a banner and with ps -e -o pcpu I can get all processes' %CPU usage. I think I would like to count the number of processes which have more than 90% CPU usage and output this number ("7" in the example) in the banner

I have p1,p2,p3,p4 some processes created by me in C. p1, p2, p3 are started individually from several consoles. And I want process p4 to terminates processes p1, p2, p3 if they are running. Which is the easiest way to accomplish that? put all processes in the same process group and send from p4 a kill signal to the group. But I couldn't do that because I cannot call successfully setpgid(getpid(), 15000) from p1-p4. It's there some way to put them in the same group? the processes don't have a child-parent relationship, they are launched manually from consoles.

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).
