    Arrow How to save terminal output?

    I would like to save the terminal output to a temporary variable.

    For example, if i execute a command to start lampp I would like to save the contents and show them with notify-send.

    I have read this

    http://www.unix.com/unix-advanced-ex...tput-file.html

    but i have no idea how to save it to a variable and then display it with notify-send command.

    Try:
    Code:
    MYVARIABLE=$(mycommands)
    Note the lack of spaces around the =. This is important.

    Entonces,

    myvar=$(sudo lampp start) && notify-send $myvar
    will be ok?

    Nothing wrong in using $myvar recursively in your example .
    Give it a try .

    works but it's better

    myvar=$(sudo lampp start) && notify-send "$myvar"
    Now, how do i turn it into a bash script?

    Like this:
    Code:
    #!/bin/bash
    myvar=$(sudo lampp start) && notify-send "$myvar"
    And save it as something.sh. After that, make it executable:
    Code:
    chmod +x something.sh
    You can put it in your ~/bin directory so that you don't have to type /link/to/something.sh, just something.sh

    You can always pass parameters to your script .
    Something like below .
    Please note that the code is not tested .
    Just trying to give you an idea to get started .
    Code:
    #!/bin/bash
    
    for option in $*
    do
            case $option in
            -m) shift
                myvar=$1
                
                shift
            ;;
            -s) shift
               server=$1
                
                shift
            ;;
            -*) echo "Invalid Option"
            ;;
            esac
    
    done
    
    myvar=$(sudo $server start) && notify-send "$myvar"
