Combine two command defined as String in variable and run as one

  • 772

Can I join two commands defined as String and run as one. E.g. 

var=$(ls -alt)
var2="| grep usersfile"
'{$var & $var2;}'
command-line bash join

  1. you can use the & operator to combine two commands.

    example:

    mkdir folder & cd folder

    But in case you want to give the first commands output as input to the second command, you can always trust the pipeline |

    example:

    ls -l | grep <keyword>
