Hello,


I installed Jboss EAP 6 on a remote Linux server in standalone mode, and deployed a HelloWorld war file successfully.

Opened a browser on my PC and pointed to...

I also learned that && means more than the traditional AND. But what does the dot mean in the...

Hello,

Can someone please help me understand the shell script below for installing Jboss EAP 6? It is from jboss-as-standalone.sh, what does the highlighted code mean?

I want to test the connectivity to an IP with Port number = xxxx.
I only know telnet can do it. For example, telnet <IP> <port>.
But I don't have telnet installed (no package) on my Red Hat Linux...

Tried "sox --i" with another audio file. The result did show A law or Mu law. The file I tried previously happened to be uncompressed (neither A law nor Mu law).

Does anyone know how to check if a .wav file is encoded with "A law" or "Mu law" in Linux and PC? I tried sox --i filename.wav on my PC, but I don't think it tell you if the file is A law or Mu law....

I know I can obtain the file names in a folder by doing the following.
ls | awk '{t=$1; print t}'

Rather than print t, I'd like to take the file name as an input to a script like
bash-3.00$...

Thanks for the responses. The awk command solves the problem:

ls -l test.* | awk '{t+=$5}END{print t}', where 5 is the column number in "ls -l" output for displaying file size.

du -sh test.*...

If I have a number of files in a directory, for example,
test.1
test.2
test.3
abc.1
abc.2
abc.3

and I need to find the total file size of all of the test.* files, I can use du -bc test.*...
