How to remove space from string?
bash, shell
Solution
Try doing this in a shell:
var=" 3918912k"
echo ${var//[[:blank:]]/}
That uses parameter expansion (it's a non posix feature)
`[[:blank:]]` is a POSIX regex class (remove spaces, tabs...), see http://www.regular-expressions.info/posixbrackets.html
Problem
In ubuntu bash script how to remove space from one variable string will be ``` 3918912k ``` Want to remove all blank space.
