# Synopsis: fixcat
# Author: Don Libes
# Description: test to see if /bin/cat is unbuffered (i.e., -u is needed)
# Return 0 if buffered, 1 if unbuffered.
#
# If this file is sitting in an architecture-specific library directory,
# then it serves as a marker that your /bin/cat buffers by default.
# test for when catting to/from files
log_user 0
spawn -open [open "|cat" "r+"]
send "\r"
expect "\r" {exit 1}
# test for when catting to real tty
#log_user 0
#spawn /bin/cat
#send "\r"
#expect "\r\n\r\n" {exit 1}
