Bashdb debug shell scripts

 

Recently, I started to learn bash shell. I don't know where to start, and I don't know any good tool packages to learn it. First look:

Yao @ wuyao :~ $ Apt-cache search bash
Apparix-console-based bookmark tool for Fast File System navigation
Backup-Manager-command-line backup tool
Bash-the GNU Bourne again shell
Bash-builtins-bash loadable builtins-headers & examples
Bash-completion-programmable completion for the bash shell
Bash-completion-Lib-programmable completion for the bash shell
Bash-doc-documentation and examples for the GNU Bourne again shell
Bash-minimal-the GNU Bourne again shell (minimal Version)
Bash-static-the GNU Bourne again shell (static version)
Bashdb-Bash debugger
Biabam-bash attachment mailer

 

We found that Bash-Doc and bashdb are documents by scholars. There are many example for reading. The latter can be used to debug shell and install them:

Yao @ wuyao :~ $ Sudo apt-Get install bash-Doc bashdb

The examples are stored in/usr/share/doc/bash/examples.
