But if I use a function: zira% tless() { less "$@"; } zira% sleep 5 | tless then "less" is left stopped in background after I type a key. bash and mksh do not have this problem (Debian's ksh93 93u+20120801-2 is completely broken as "less" is immediately put in background). -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
