Editing Sed (section)

===Other simple examples===
<!-- please avoid the use of GNU sedisms. These are non-portable and lead to bad code -->
Below follow various sed scripts; these can be executed by passing as an argument to sed, or put in a separate file and executed via <code>-f</code> or by making the script itself executable.

To replace any instance of a certain word in a file with "REDACTED", such as an IRC password, and save the result:
<syntaxhighlight lang="shell-session">
$ sed -i "s/yourpassword/REDACTED/" ./status.chat.log
</syntaxhighlight>

To delete any line containing the word "yourword" (the ''address'' is '/yourword/'):
<syntaxhighlight lang="sed">
/yourword/ d
</syntaxhighlight>
To delete all instances of the word "yourword":
<syntaxhighlight lang="sed">
s/yourword//g
</syntaxhighlight>
To delete two words from a file simultaneously:
<syntaxhighlight lang="sed">
s/firstword//g
s/secondword//g
</syntaxhighlight>
To express the previous example on one line, such as when entering at the command line, one may join two commands via the semicolon:
<syntaxhighlight lang="shell-session">
$ sed "s/firstword//g; s/secondword//g" inputFileName
</syntaxhighlight>
