I am using gawk as well and I get only the first line on the terminal output.
Code:
2) the while loop tries to read a line at a time from for_later.txt until an error. This reads only the first line (output by 1) and prints it.
So, is there any way to "force" or bypass the error exit status of getline and set it to 1 in order to keep reading the remaining line of "for_later.txt"?
I was simply trying to redirect some output in a log file but it foxed me.
truss a.out > log
It gave only the output of the a.out which was only a simple print "Hello"
Then I tried
truss a.out 2&1>a
echo `truss a.out` > a
All failed.
What am i missing.
Thanks (7 Replies)
