   • List out all the Shells Using Linux Commands

     There are various methods to list all the shells which are installed in our Linux system. A Shell is a software program that acts as an interface between the user and the operating system(OS). It can also be thought of as a command interpreter that is used to execute another program.

     Method 1: Using cat command

     Example:

     cat /etc/shells

     Using ‘cat’ command

     Explanation: The list of all the shells which are currently installed in our Linux system is stored in the ‘shells’ file which is present in /etc folder of the system. It has read-only access by default and is modified automatically whenever we install a new shell in our system. As we can see, the cat command displays the various installed shells along with their installation paths.

     Method 2: Use of grep command with Regular Expressions.

     Example:

     grep '^[^#]' /etc/shells

     Using ‘grep’ command

     Explanation: Regular Expressions are one of the most powerful tools that come in handy when handling complex expressions. We can use regular expressions with grep command to display all the shells installed in our system as shown above.

     You can use the bash(1) built-in compgen

     • compgen -c will list all the commands you could run.
     • compgen -a will list all the aliases you could run.
     • compgen -b will list all the built-ins you could run.
     • compgen -k will list all the keywords you could run.
     • compgen -A function will list all the functions you could run.
     • compgen -A function -abck will list all the above in one go.

     Check the man page for other completions you can generate.

     To directly answer your question:

     compgen -ac | grep searchstr-

     should do what you want.

     Add to .bashrc

     function ListAllCommands{ echo -n $PATH | xargs -d : -I {} find {} -maxdepth 1 \ -executable -type f -printf '%P\n' | sort -u}-

     If you also want aliases, then:

     function ListAllCommands{ COMMANDS=`echo -n $PATH | xargs -d : -I {} find {} -maxdepth 1 \ -executable -type f -printf '%P\n'` ALIASES=`alias | cut -d '=' -f 1` echo "$COMMANDS"$'\n'"$ALIASES" | sort -u}-

     There is the

     type -a mycommand-

     command which lists all aliases and commands in $PATH where mycommand is used. Can be used to check if the command exists in several variants. Other than that... There's probably some script around that parses $PATH and all aliases, but don't know about any such script.
