cli-sedHow do I use a CLI sed query?
The sed
command is a powerful utility for editing text files from the command line. It can be used to perform complex search and replace operations.
To use sed
, you must provide a query string that describes the search and replace operations you want to perform. Here is an example of a sed
query:
sed -i 's/old_word/new_word/g' file.txt
This query will search for all instances of old_word
in file.txt
and replace them with new_word
. The -i
flag tells sed
to edit the file in-place.
Here is a breakdown of the command parts:
sed
: the command itself-i
: the flag that tellssed
to edit the file in-places/old_word/new_word/g
: the search and replace query, which consists of:s
: the search and replace operationold_word
: the word to search fornew_word
: the word to replace withg
: the global flag, which tellssed
to replace all occurrences ofold_word
file.txt
: the file to edit
For more information on sed
, see the GNU sed Manual.
