I have been trying to get the output of an ssh session pushed to file... the problem is that there are colors in the output, and when I view the file the colors show up as "^[00m" or other such various nonsense
The weird part is that if I do this all manually, I have no problems, but if I try to... (0 Replies)
I have a simple csh-script on a Solaris Workstaion which invokes the bc calculator:
#!/bin/csh
set shz=2
set zshift=5
set shzp=`bc -l <<END \
scale = 3 \
-1. * $shz + $zshift \
END`
echo $shzp
The result ($shzp) in this case is 3 (-1*2+5). It works fine on Solaris 8.

tty
TTY(4) Linux Programmer's Manual TTY(4)NAME
tty - controlling terminal
DESCRIPTION
The file /dev/tty is a character file with major number 5 and minor number 0, usually of mode 0666 and owner.group root.tty. It is a syn-
onym for the controlling terminal of a process, if any.
In addition to the ioctl(2) requests supported by the device that tty refers to, the ioctl(2) request TIOCNOTTY is supported.
TIOCNOTTY
Detach the calling process from its controlling terminal.
If the process is the session leader, then SIGHUP and SIGCONT signals are sent to the foreground process group and all processes in the
current session lose their controlling tty.
This ioctl(2) call works only on file descriptors connected to /dev/tty. It is used by daemon processes when they are invoked by a user at
a terminal. The process attempts to open /dev/tty. If the open succeeds, it detaches itself from the terminal by using TIOCNOTTY, while
if the open fails, it is obviously not attached to a terminal and does not need to detach itself.
