Package: less Version: 418-1 X-Debbugs-Cc: [email protected] Man says -F or --quit-if-one-screen Causes less to automatically exit if the entire file can be dis- played on the first screen.
However this is not true, try $ LESS=XF less +G /etc/services $ seq 111|LESS=FMXi less +G They don't fit on the first screen but end less nonetheless. Using plain LESS=F is even worse. They then seem like no-ops on my xterm. The screen is restored before you notice anything. Only with $ seq 1111111|LESS=F less +G does the screen blank long enough so you know something happened. Anyway, we were trying to solve http://permalink.gmane.org/gmane.comp.version-control.git/103228 Say, why can't less have an xargs-like --no-run-if-empty -r If the standard input does not contain any nonblanks, do not run the command. Normally, the command is run once even if there is no input. This option is a GNU extension. But for zero bytes of input. I.e., less senses that input has closed already at the 0th byte, and just exits without sending a single curses character to the terminal. Gee, never thought a simple pager program would end up not so simple... but that's reality. P.S., _ (Underscore.) Followed by one of the command line option let- ters, this will print a message describing the current setting of that option. The setting of the option is not changed. add a --dump-settings to dump them all at once. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
