http://unix.stackexchange.com – Consider such code: echo hello >> log.txt echo world >> log.txt I execute command with stdout redirection. Is it possible to create sticky redirection? Something like this: redir stdout log.txt echo hello echo world stop-redir This would be equivalent to the first piece code. What I really need -- make such sticky redirection for stdout and stderr (at the same time), execute some commands, stop redirection, and read log file. (HowTos)
