I have a bash variable that has an extra space before the text and I can get rid of it by doing

echo "$myvar" | xargs

However, I want to store the variable that has the '| xargs' applied to it as another variable as opposed to echo so I can use it for something else.

`newvar="${myvar# *}"`? – Cyrus Apr 11 '19 at 18:35

that does not work – Tuhaid Asif hussain Apr 11 '19 at 18:40
`read newvar <<< $myvar` without quotes will strip whitespaces. I suggest you show your code and data samples with existing input and desired output. I don't like using `xargs` without a command to run - not its intended use... – Paul Hodges Apr 11 '19 at 19:34
