Is there a way to process the output of a locate command on the spot within bash. The output is 3 lines, ex:

I need to pipe the output of date command, to form a command like this:

I have an OLED screen on my laptop that I have configured to show status information. The current driver I have installed in Linux for it is able to display messages by sending them to a script as an argument separated by spaces.Example: the command /opt/asusg50oled/utils/notify.sh Hi Everybody "Hello World" displays on the oled screen:
Hi
Everybody
Hello World
If another message is sent before the old ones disappear and it reverts to status info, it pushes off the top message. Example: less than 30 seconds after the previous example, /opt/asusg50oled/utils/notify.sh "Bananas have potassium" is executed:
Everybody
Hello World
Bananas have potassium
What I want to do is have kernel messages (the kind you see by running dmesg) forwarded to this script. For example, when I insert a USB drive, the following information would show on the OLED screen as they're logged:........
In a terminal in OSX I can pipe output to pbcopy and then go into a web browser and paste it. I tried this in Linux with xcopy but when I switch to the browser it just overwrites the clipboard with with whatever was in it the last time the browser was used. What works like pbcopy in Linux?

I am trying to automate some directory naming when we're manually running some scripts and are using tee to direct the output to a file (log). Right now this is what we do
Code:
./some_script.sh 2>&1 | tee /home/user/some_dir/logs/manual/some_script_20110216_1628.log
As a matter of laziness and keeping the log files consistently named, I'd like to create a function to pipe it to so that it's doing all the naming How I envision the command running
Code:
./some_script.sh 2>&1 | myfunc
And what the logfile name should look like (and in the right directory)
Code:
some_script_20110216-1628.log
I was thinking of adding a function to our profile to handle this. Just in testing I was trying to stream line right on the command line, but I'm having some difficulty in getting the name of the script that is pushing data over the pipe. Here is what I've tried
Code:
./some_script.sh 2>&1 | tee $(cd ../logs/manual; pwd)/$0_$(date +%Y%m%d)-$(date +%H%M).log
but that created a file named
"bash_20110216-1628.log"
For instance, suppose I want to pipe the output of ps -A to a gtkdialog table.

I know that in Z shell its really easy. omething like: Code: echo "test" >> file1 >> file2 Would work. But in Bash it doesn't seem that easy. I know that tee will send the output to 2 files but it also sends it to STDOUT.Something like:Code: echo "test" | tee -a file1 file2 Would put the word "test" in file1, file2, and STDOUT. Is there a way to just send the output to file1 and file2?

I normally use the "locate" command to find files that I have on my local drive. However, if I wanted to do this for an external drive, how would I go about this?
From what little I know about Linux, I'm guessing that it creates a reference file from which it performs the search when the command is typed. If I'm right this is updated at a given interval or when "updatedb" is used?
As the external hard drive is not always mounted is it best to create another of these reference files and have a different command (e.g. locateext) or something? Or is it best to add the external hard drive's location to the list of files that get added with updatedb.

View 4 Replies View RelatedI understand that $! is the PID of a command. For example:
Code: #!/bin/bash
myprogram &
echo "PID of myprogram is $!"
I'd like to send the output of "myprogram" to both console and to a log file using the "tee" command but I also want to store the PID of "myprogam". Something like this:

The problem is that $! is now the PID of "tee" rather than the PID of "myprogram".
I've written a simple server in linux used fork to create a FIFO pipe.The server create two FIFO pipe.One for server read data from client and write data to client.Then another pipe for client read data from server and write data to server.When the server read data from a client used server-pipe and then write data to client.But ,if the client no read open the pipe,the server side write will be crashed because of a broken-pipe SIGPIPE. How to check whether the read side is opened?Or,how to catch the SIGPIPE,and then my server will still execute on,not crashed!!
