| | ====== ed Cheat Sheet ====== |
| |
| | ed is a small, powerful, line-oriented, command-line-interfaced text editor. All editors frustrate, but ed often amazes while others disappoint. |
| | |
| | [[http://www.gnu.org/fun/jokes/ed.msg.html|ed, man! !man ed]] — ed is the standard text editor. |
| | |
| | "man ed" for more information. |
| | |
| | Start ed from your shell command line: |
| | |
| | "ed //file//" |
| | |
| | Edit file by entering ed commands with the following syntax: |
| | |
| | "[//range//][//command//]" |
| | |
| | //range// specifies the line or block of consecutive lines (syntax: "//from-line//,//to-line//") to which //command// is applied. Default range is the current line except where noted below with a parenthesis preceding the command syntax. Lines are specified as follows: |
| | |
| | | //n// | line //n// | "." | current | "$" | last | "'"//c// | mark //c// | |
| | | "-"[//n//] | up //n// (default: 1) | "+"[//n//] | down //n// (default: 1) | "," | 1,$ | ";" | .,$ | |
| | | "?//re//?" | previous regexp match |||| "///re///" | next regexp match ||| |
