Looking for the proper way to bring a string into the stdin. I have a string that I would like to grep and awk. Each have to be run separately, not piped together. So far, the only way I could figure out how is to echo the string and pipe it:
My supervisor keep getting "stdin not tty" or something like that when he pipe or redirect input into a program. Others
don't seem to get this message. Is there some way I can help him to fix or turn this off?
Thx in advance (1 Reply)
can you redirect STDIN with command arguments?
I have tried this approach:
# ./script -option <argument1> <argument2> 0<$2
# $2: ambiguous redirect
Is this possible? (4 Replies)
