Re: How do you clear the current line?

print "^[[K";
[download]

(that's "ESC[K") will clear from the current curson position until end of line.

Update: Yes, tye, directly cut and pasting the above will not work (hence the added description of "that's 'ESC[K'") (it was embedded as an ESCAPE using my text editor). To get an ESCAPE in Perl, you'll need to use "\e".

`print "^[[K";` gives me: `^[[K` perhaps you meant: `print "\c[[K"; # or print "\e[K";` [download] but be aware that those will only work for ANSI-ish terminals (which are pretty common, though). - tye (but my friends call me "Tye")	[reply] [d/l] [select]

That's exactly what I'm looking for. I guess that explains all the weird ^[[D type output when pressing the cursor keys without anything tied to stdin. I have a couple questions though... how compatible is this escape sequence? I am targeting as many POSIX compatible machines as possible. I would use Term::Cap, but I know that many systems are phasing out termcap completely, including Debian GNU/Linux and AIX. Obviously it would be better to find out the exact character that the term expects based on it's TERM type, but termcap is the only mechanism I know for doing as such. Also, is there a full list of all the possible escape characters like this one? Thanks, Nicodemus	[reply]

That's a fairly basic ANSI sequence: existing long before Termcap or Termlib (way back to pre-1980 machines). I used this for the lookup of the sequence you were looking for. Normally, I just consult a very old Z80A programming manual I have lying around someplace.	[reply]
