Commands tagged tty (3)

  • Debug SSH at the Maximum Verbosity Level

    When debugging an ssh connection either to optimize your settings ie compression, ciphers, or more commonly for debugging an issue connecting, this alias comes in real handy as it's not easy to remember the '-o LogLevel=DEBUG3' argument, which adds a boost of debugging info not available with -vvv alone. Especially useful are the FD info, and the setup negotiation to create a cleaner, faster connection. Show Sample Output

  • Alias to securely run X from tty and close that tty afterwards.

    There are different ways to run X, I prefer to run it without xdm/gdm. The problem is you can't lock X because one can press Ctrl+Alt+F1, press Ctrl+Z and kill you X locking process. Of course you can disable Ctrl+Alt* or Ctrl+Alt+Backspace keys, but it's inconvinient if you really need to switch into console.

diff the same file in two directories.
This is useful when you're diffing two files of the same name in radically different directory trees. For example: Set $ path1='/some/long/convoluted/path/to/all/of/your/source/from/a/long/dead/machine' then $ path2='/local/version/of/same/file' then run the command. Much easier on the eyes when you're looking back across your command history, especially if you're doing the same diff over and over again.
