1
1 If the terminal hangs up, 'ed' attempts to write the buffer to the file
1 'ed.hup' or, if this fails, to '$HOME/ed.hup'.
1
1 'ed' processes FILE arguments for backslash escapes, i.e., in a
1 filename, any character preceded by a backslash ('\') is interpreted
1 literally.
1
1 If a text (non-binary) file is not terminated by a newline character,
1 then 'ed' appends one on reading/writing it. In the case of a binary
1 file, 'ed' does not append a newline on reading/writing.
1
1 Per line overhead: 2 'pointer's, 1 'long int', and 1 'int'.
