xargs needs a -n switch for that though - or does it not?	[reply]

The xargs program shipped with my Debian GNU/Linux system knows about the command line length limitation, and automatically wraps too long command lines into muliple programs. You can see the length limits easily: `$ xargs --show-limits Your environment variables take up 2038 bytes POSIX upper limit on argument length (this system): 2093066 POSIX smallest allowable upper limit on argument length (all systems): + 4096 Maximum length of command we could actually use: 2091028 Size of command buffer we are actually using: 131072` [download] And to show that it does not produce an error, I create a command line that's 20 times that limit: $ yes \| head -n 20910280 \| xargs /bin/echo > /dev/null $ [download] Perl 6 - the future is here, just unevenly distributed	[reply] [d/l] [select]
