I have found a problem using less and grep to search a file. The file is
available at: http://www.cis.ohio-state.edu/~sears/file.txt (It is over 1
megabyte, so I did not include it in this message.)
I am using bash, and a complete, current installation of cygwin.
When I run the command `less file.txt | grep cygwin` it sometimes fails to
find a match in the file, even though the file does contain the string.
It seems to be sporadic, but I have been able to reproduce the problem on
three machines, each of which ran at about 700mhz. Other commands that
seem to work as expected follow:
less file.txt | cat | grep cygwin
cat file.txt | grep cygwin
grep cygwin file.txt
If you have difficulty reproducing the bug, try running the command
multiple times (eg: by repeating <up-arrow>, <enter> rapidly). Some
installations will only rarely have a problem, others will rarely yield
the correct result. On systems that usually produce the correct result,
re-running the command rapidly seems to increase the likelihood of the
problem
ocurring.
Also, the string "cygwin" always appears at the end of a line in the file,
which may be related to this bug.
I have tried both version 1.1.8 and the current cygwin distribution.
(1.3.2) Both seem to suffer from this problem.
As a control, I've checked this against a Linux system, and the bug did
not exist there.
Below, the mount mode is listed as textmode. The bug exists under binmode
as well.
Here is the output of cygcheck -s -v -r > cygcheck.out:
