General :: Expanding Globs In Xargs?
Jun 29, 2011I have a directory like this:
mkdir test
cd test
touch file{0,1}.txt otherfile{0,1}.txt stuff{0,1}.txt
I want to run some command such as ls on certain types of files in the directory and have the * (glob) expand to all possibilities for the filename.
echo 'file otherfile' | tr ' ' '
' | xargs -I % ls %*.txt
This command does not expand the glob and tries to look for the literal 'file*.txt'
How do I write a similar command that expands the globs? (I want to use xargs so the command can be run in parallel)

General :: Xargs - How Some Command Receive Input From Both Sides
Mar 9, 2010I would like to ask the following:
1) ls -l |grep test -> this will grep every "ls -l" output line
2) ls -1 |xargs grep test -> this will grep every single file with test
3) ls -1 |xargs echo -> this will echo directory list
4) ls -1 |echo -> this does nothing!!!
My question is: how some command can receive input from "both sides" (grep can grep whole output or every single file - xargs, the same is for i.e. wc command). 4) echo does nothing (it's a single echo command).

Sep 26, 2010I execute an application from a script file and redirect stdin to it from here-doc like this:
my_cli << HERE_DOC
enable
configure

exit
exit
HERE_DOC
This works as expected, but I don't see neither the input nor the app output. The application is an interactive prompt written in C. When I interact manually with it, I see the prompt itself and responses to my input, but when I execute the aforementioned script I see nothing. I would like it to print the input and the output as if a real user was typing. Do you know how to achieve that?

Feb 25, 2010I'd like a function in my .bashrc file that would allow me to pass text to it and echo the text to a specified file. I know it's simple as "echo 'text' >> file," but ideally, I would want to alias the function so I execute something like:
Code:
user~ $ write 'this is a test' with "write" being the function, and 'this is a test' being echoed to the file. I hope I explained that well enough.

Jun 21, 2011I'm trying to create a shell script to take an argument and use it to name a terminal tab. So if the script's name is tabnm, tabnm "test" should rename the current tab "test"
This is my code:

robin@icarus $ sh tabnm.sh test

If I just run echo -ne "e]1;Testa" straight in the shell, the tab is renamed.

Sep 16, 2010We're going to be doing a rather large server deployment, and using the provisioning system we have in place there is no current way to just "copy" a file over to the servers. All files/scripts have to be run from the provisioning server.Due to network constraints, the provisioning system can't run a script we need to run (requires certain network assets to complete, but as soon as we modify the network settingshe provisioning system loses access to the server and can't run the script). So,our network configuration script to create the other script on the server in /root when it runs.My original method was to do something along the lines of:
