Limits
Portability
However, there is no remembered filename at present. Run the
subcommand again, but specify a filename this time.
Restricted shell
The command line invoked the restricted form of ed, but you tried an action
that was not allowed in the restricted editor (the ! subcommand).
Temporary file error
You ran out of space on disk or encountered other errors involving the page
file stored in the temporary file.
Warning: file not saved
You entered a subcommand to quit editing the current file, for example, q or
e to edit a new file; however, you have changed the file since the last time
you saved it. ed is suggesting that you save the file before you exit it;
otherwise, your recent changes will be lost. To save the file, use the w
command. If you really do not want to save the recent changes, use q to
quit or e to edit a new file.
?file An error occurred during an attempt to open or create file. This is applicable
to the e, r, and w subcommands.
? An unspecified error occurred. Use the h or H subcommand for more
information. If the input to ed comes from a script rather than from a
workstation, ed exits when any error occurs.
ed allows a limit of 1024 bytes per line and 28 000 lines per file. It does not allow
the NUL ('\0') character. The maximum length of a global command is 256
characters, including newlines.
POSIX.2, X/Open Portability Guide, UNIX systems.
The addresses < and >, the –b option, and the W and X subcommands are
extensions of the POSIX standard.
