ed is a small, powerful, line-oriented, command-line-interfaced text editor. All editors frustrate, but ed often amazes while others disappoint.
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 | |||||
| “a” | Append after. | “c” | Change range. | “i” | Insert before. | “.” | End input mode. |
| “d” | Delete. | "s/re/s/[g|n][p]" | Substitute. |
| “m[line]” | Move after line. | “t[line]” | Copy after line. |
| “(.,+)j” | Join lines. | “u” | Undo. |
| “(1,$)g/re/cmds” | Perform cmds for all matching lines. | “(1,$)v/re/cmds” | Perform cmds for all non-matching lines. |
| “e [file*]” | Edit file. | “E [file*]” | Edit, discarding changes. |
| “($)r [file]” | Read and append. | “f [file]” | Set/display file name. |
| “(1,$)w [file*]” | Write. | “(1,$)W [file*]” | Append to file. |
| “(1,$)wq [file*]” | Write and quit. |
| * | In place of file, specify “”!“shell-command” to read/write text to shell-command standard output/input. |
| “p” | List lines. | “l” | … with unprintables. | “n” | … with numbers. |
| “(+)z[lines]” | Scroll. | “(+)null” | “p” |
