UNIX Commands

These are some interesting UNIX Commands are used during the middleware administration.

1. To set the “tree” alias to list all the directory in the UNIX terminal as tree structure.

tree=’ls -R | grep :$ | sed -e ‘\”s/:$//’\” -e ‘\”s/[^-][^\/]*\//–/g’\” -e ‘\”s/^/ /’\” -e ‘\”s/-/|/’\’

Output of the above command is like this:

/home/mqm$tree
|-mqsc_scripts
|—logs
|-omegamon
|—Deploy
|—InstallITM
|—–plugin
|——-plugins
|—REPORTS

2. “find” command.
One of the useful command to find the files and directories in the UNIX file system is “find” command. The find command takes the following argument to identify the files or directory in UNIX file system.

find . -type f -print -exec grep -i “type your string here to find” {} \;

To find out the result and we can use the output to filter the result strings.

find . -name *.txt | xargs du -h|grep -i M

The below command gives the same output, but we can not use the output to other grep commands.. (may be I don’t know how to use that)

find . -name “test*” -exec du -sh {} \;
