ex(1) ex(1)
By default, ex shall start in the command mode, which shall be indicated by the ":" prompt. The input
mode can be entered by append, insert,orchange commands. There is one other mode, visual mode,
in which full screen editing is available. This is described more fully under the visual command. The
command line can consist of multiple ex commands separated by vertical-line characters(|). The use of
commands that enter input or visual modes in this manner, unless they are the final command on the line,
produces undefined results.
Command lines beginning with the double-quote character (") shall be ignored. This can be used for com-
ments in an editor script.
WARNINGS
The undo command causes all marks to be lost on lines that are changed and then restored.
The z command prints a number of logical rather than physical lines. More than a screenful of output can
result if long lines are present.
Null characters are discarded in input files and cannot appear in resultant files.
On some systems, the recovery of an edit file with the -r option is possible only if certain system-
dependent actions are taken when the system is restarted.
Edit preserve files can only be recovered on systems running the same HP-UX release in which they were
preserved. Preserve files are not recoverable across different releases.
On HP terminals, the attribute field of any function key specified by a map #
n ... command should be set
to
normal rather than to the default of transmit.
Do not use the -C option to edit unencrypted files. The -C option is meant to be used only on files that are
already encrypted. If the
-C option is used on files which are not yet encrypted, a write in the edit session
is likely to corrupt the file.
For information about line length limits, file size limits, etc., see the WARNINGS section of vi(1).
EXIT STATUS (XPG4 Only)
The
ex utility shall exit with one of the following values:
0 Successful completion.
>0 An error occurred.
AUTHOR
