To remove all spaces from all files in the current directory
linux rename remove spaces
rename "s/ //g" *
how to replace part of the text with another (it is almost like using sed):
rename s/"Screenshot at 2019-04-22 "/"AC97-Windows-InstallSolution"/g *
The first part "Screenshot at 2019-04-22" is what we're looking for
The second part "AC97-Windows-InstallSolution" is what we're replacing it with
the g after the slash / means replace all occurrences
The * means apply it to all files but we could easily have used something like *.txt or *.png or any other type of regular expression.
The above won't work in Centos but in Debian based distros like Ubuntu, Mint etc as rename in Centos doesn't work that way.
