Full Discussion: Event logging to file and display to console | tee command is not able to log all info.
Top Forums Shell Programming and Scripting Event logging to file and display to console | tee command is not able to log all info. Post 302602491 by DGPickett on Monday 27th of February 2012 01:50:59 PM

For instance, if some line does something this, stdin and stdout are changed, no longer default to the display:
Code:
exec > /tmp/stdout.$$ 2> /tmp/stderr.$$

(A bad practice, in my view, as it confuses readers of subsequent lines. If you want to redirect for a while, put that bit in () or {} and redirect just that bit, temporarily.)
