perl -pi~ -e ’s/regexp1/regexp2/’ files

Where;

  1. regexp1 - Regular expression you are seeking.
  2. regexp2 - It’s replacement.
  3. files - The files you wish this replacement to occur.

let x=0 | g/regexp/let x=x+1
echo x

where regexp obviously is the regular expression (pattern) you wish to count.
