General :: CLI Commands To Generate Random Result From Specified List?

Jul 20, 2011

List of 77 lines with the names of movies. For ease, let's say it's in a text file. What I want is a command line argument I can pass that'll read each line and pick one of those 77 lines at random, except I can't figure out how to do this. Is there a program I can just pipe the output of 'cat listofmovies.txt' to?

General :: Generate Random List And Determine Size Of Arbitrary Block Of Files In Dir?

Mar 4, 2010

I want to generate a temporary random list from a directory of files and then determine the size of an arbitrary block of files from this list (say 1-25 or 26-50) and add their names to a file along with some other info for each name. I can generate a random list with file sizes like this: ls -l | sort -R | cut -d " " -f 6 but i'm not sure how to add up the sizes of just a certain block of these files and at the same time save the file names.

General :: Generate Random Number Either 1 Or 0?

Jan 21, 2010

Not only that but I need tons and tons of them generated, and I need it to be totally random each time.

matthew@mvm:/h/misc> cat a
for i in {1..5}; do
echo $RANDOM


There you can see that it is the same number. It does that every time!! Grrr. The strange thing is each time I manually type [or copy & paste] it into the terminal, it gives random [not static, like I am getting from my script] results.

The reason I want this is because I am making a script where this line will randomly go up or down [depending on if the random number is 1 or 0].

General :: Capture A List Of All Installed Commands?

Jan 30, 2010

if I open a terminal and hit [TAB] [TAB] it will display "Display all 2583 possibilities? (y or n) ". If I press y is there a way to capture the output and write it to a file? Not like it is a command so I can't just use a redirect to a file? If not I guess I could just do an ls on all locations of $PATH and capture that to a file.

General :: SSH Tunnel Commands To List Active/disconnect?

Apr 1, 2010

I've just started experimenting with SSH tunnels. I wanted a way to connect to MySQL on our website VPS but wanted the connection encrypted rather than just using PHP's mysql_connect() function and connecting to the remote IP. This seems to be working great. I'm also looking into autossh to make sure that the tunnel gets reconnected when it there a command/utility that can list the currently active SSH tunnels? Be great if there was a way of terminating an active tunnel through a command as well. Or is it a case of manually digging through the process list and killing the specific PID like I have been?

Debian :: Generate Directory List With Exclusions?

Aug 18, 2011

I'm trying to generate a list of my music directory folder structure WITHOUT the files included. I have my music directory set up in a hierarchy of Artist>Album>Files, and I just want to generate a list of the folders because that will, in effect, output a list of what albums I have by what artists, which is ultimately what I'm after. I did some looking on the internet through various forums over the past few days and found two ideas that looked promising, but ended up being not exactly what I needed. The first was to generate a .txt file based off of a shell ls command:

ls -R [music directory name] >> ~/mymusiclist.txt

That's great, except that it also includes the 40,000+ individual music files by name. I'm not about to invest that much time editing the files out of the list when I know there has to be an easier way.The second idea I came upon involved using the extglob function. I tried enabling extglob and using it to input a "negative wildcard" into the above method to remove anything .mp3 from the returned list, but extglob didn't play well in that context. I'm not a command line wizard, so it's entirely possible that I'm missing something fairly obvious. In fact, I'm sure I am. So this is a great opportunity for me to learn something new. If anybody knows of a command line way to do this, I'd love to know it. Or, even better, if anybody knows of an app that can do this, even better. I'm not above installing a secondary music player just to import the library once and get my list.

General :: Using The Expect And Send To Execute List Of Commands Inside A File?

Feb 2, 2011

i am working on some kind of PBX and i have list of telephone numbers inside a file, i have to insert these numbers into the correct command and then telnet to a remote server and execute these commands. i can read the telephone numbers and insert them into the command with no problem, but when i try to insert these commands into the send i face problem. here is the basic code

read msisdn < input


i can make external loop inside the Bash which read the input file and issue the command and then telnet and execute, but this will make the script connects and disconnects again for each line which cause high load on that server and hardwar problem. i am wondering if there is an option inside the expect interperter which makes the send read directly from a file... somthing like this:

expect "<"
send "input-filename
expect "<"
expect eof
