General :: Reusing Find Command Results In Mplayer Arguments?
Jan 22, 2010
I wanted to supply mplayer with the output of find command as arguments. The error returned showed spliced names of files whenever spaces occurred. I have subdirectories in my /home/my_user_name/Music/ directory, and in them multiple *.oga music files. The actual command that I issued was
mplayer started but then was looking for broken file names. I am thinking quoting has to do with it to preserve the filename as one string but different attempts were met with inroads:
Code:
mplayer `find /home/my_user_name/Music/ -name "*.oga"`
gave me the same result and
Code:
mplayer `"find /home/my_user_name/Music/ -name *.oga"`
I'm timing how long it takes to run a command foo. I'm looking to append the results from the time command to a file, and discard the results from the foo command. I tried the following, but it didn't do what I want:
$ time ./foo > /dev/null >> output_from_time_command.txt
I am able to start up firefox just fine out of my terminal, but i have not been able to find any list of arguments that can be added in the command line. what i'm looking for is that it starts up in Full Screen mode right off. is there an argument that can be added to ti to do that?
I'm pretty sure this is super simple, but I've searched and searched and for the life of me I can't find any info on how to limit the columns that display in the interactive top program with arguments passed from the command line. I recall seeing something formatted like this ...
~/top -f (kdx)
Which would only show the %CPU, UID, program name fields/columns. I'd like to display the results in a really narrow terminal window on the right side of my desktop.
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.)

so I was wondering how I could do a simple find which would order the results by most recently modified. Here is the current fine I am using. (I am doing a shell escape in php, so that is the reasoning for the variables. find '$dir' -name '$str'* -print | head -10
How could I have this order the search by most recently modified. (Note I do not want it to sort 'after' the search, but rather find the results based on what was most recently modified)
Write a script that will take a list of filenames as arguments and output a count of how many of them are regular files, and how many of them are scripts (if the file is executable, it will be assumed to be a script file)
I'm trying to do a find /photos/* -type f -mtime +365 to find all my pictures that are over a year old, but I keep getting argument list too long. How can I view what all the results are, even if it just dumps it to a file that I have to open?
Below is an example output of what I see when I run the 'ls' command on some directories in linux (this is from a tomcat/common/lib directory). However I'm not clear on why some of the filenames are appearing inside [square brackets]
This question may be silly and super easy for linux connaisseurs, but I was just wondering, for instance, I want to use the >find command to search for a file and send the results to a text file
If I do something to the effect of this:ldapsearch -b "dc=example,dc=com" -x -z 3000
I'll get this back at the end of the result set: # search result search: 2 result: 4 Size limit exceeded
The thing is is that I have way more (thousands) than what's being displayed here. And I've tried to mess around with /etc/ldap.conf, changing the SIZELIMIT directive to something else, 10000, let's say, and restarting the server, but the same goddamn thing happens.
I've been messing around with this for quite some time now, hopefully someone will be able to shed some light on this so that I can learn my way out of this mess that is LDAP. Also in a related matter, I'm running Mint (based off of Ubuntu), and all the documentation that I've seen (probably read a good 100+ pages in a few days now on this) keeps telling me to make changes to my slapd.conf file. What slapd.conf file? It doesn't exist, I can't find it at least. find / -name slapd.conf turns up nothing.
how to include my command results in a script? Basically what the script does is it checks the status of a service within the linux server, then sends an email when done. I want to include the results of my status check to my mail when sent.
i.e. service dhcp3-server status Status of DHCP server: dhcpd3 is running. <---this I want to include in the mail that is sent out via script.
I want to know how to get eg. the contents of a form on a webpage which has been passed to a server side PHP script, inside for example an array which I can read. I've been reading a ebook on PHP which as far as I can see doesn't cover this inside it.
I am calling another executable in my application (C programing) using "system" command which is user interactive program. now i want to pass those args in system command only.
system(" executable ");
Executable will expect 1,2 or 3.
1 is to continue 2 for do changes in settings 3 exit from application
I am having trouble trying to get the kernel to accept some command line arguments for parport_pc during bootup. I have a custom base board with a PC-104 CPU board connected to it through the ISA bus. On the base board I have 3 parallel ports mapped to addresses, 0x150, 0x158, and 0x160. Only the first one needs interrupts, the second two do not. So, on bootup I load the parport_pc module like this modprobe parport_pc io=0x150,0x158,0x160 irq=3,none,none I have been running an older RedHat kernel, 2.6.11 for the past few years and this has been working flawlessly. I had the above modprobe call in /etc/rc.d/rc.local.
Now I am trying to set the system up to use CentOS 5.5, kernel 2.6.18-194.el5. What happens is, the module inserts OK, but the system never recognizes the ports. (i.e, they do not show up in /proc/ioports) But, if I log into the system, then rmmod parport_pc, then re-modprobe it as above, it works just fine and now my ports are visible. This is an embedded system, expected to just come up and run, so kicking it into action by hand is not an option.
I have tried putting a parport_pc.modules file in /etc/sysconfig/modules so that it will be seen by rc.sysinit, (some site I found while googling said modprobes need to be done earlier than in rc.local),and again, the module gets inserted but the ports are not seen. I have also tried putting rediculously long pauses between each step of the modprobing of the parport stuff;
how to use QGLviewer. I want to give my program a file name as a command line argument. All of the sample programs I find have a main.cpp file like this:
Quote:
#include <QApplication> #include "window.h" int main(int argc, char *argv[])
[code]....
Then the Window class, which is derived from QGLViewer, does all the program's actual work. If I want access to argc and argv, for example, to open and read a file that's passed as an argument, what would handle that? Is there a built-in way to get the arg variables to the window class, or do I need to just write a loadfile function and pass them?
I have recently installed MySQL Server on my CentOS box.
CentOS 5 MySQL 5.0.45 (installed using 'yum install mysql-server') I can start the daemon without error by issueing the following command: service mysqld start
The problem is that I want to use a number of the command line options available to mysqld, such as --verbose and When I issue '/etc/init.d/mysqld --verbose --help' I get the following output:
I have 4 Linux machines with cluster.My target is to find all kind of IP address (xxx.xxx.xxx.xxx) in every file in the linux system remark: need to scan each file in the linux system and verify if the file include IP address if yes need to print the IP as the following
I am trying to do a find/grep/wc command to find matching files, print the filename and then the word count of a specific pattern per file. Here is my best (non-working) attempt so far:
Is there a way to specify to find that I only want text files (and not binary files)? Grep has an option to exclude binary files, so I thought find probably has a similar feature, but I've been unable to find it.
Has anyone used rtmpdump or flvstreamer? They compile well (there is also a package on Packman for rtmpdump, but not for the latest version) and have man pages listing a bunch of command line arguments, but I have not yet figured out how to use them in connection with browser and flash plugin.
I'm having problems with bash quoting. Maybe someone can tell me what's going on.. Basically, I need to create a command line inside a bash script that contains arguments that contain spaces and bash variables that need to be expanded.
