Linux Terminal Basics: Sed – Find & Replace

Sed (Stream EDitor) can be used to Find & Replace words and regular expressions within Files or Bash Variables / Arrays.
In this tutorial I cover the basics of Sed, including replacing letters, words, editing a file, and replacing a character at a specific position in a string.

Command:
sed ‘s/regexp/replacement/’ file

/g Global (multiple changes per line)
-i Edit file inline
-E Extended regular expression
