Read iTerm2 last session output history

For anyone who ends up on this page, I realized I should post the answer:

Using launchd instead of cron does indeed fix the authorization problem. Your user launchd jobs (which run only when you are logged in) correctly use the SSH agent information that was unlocked via your keychain as part of login (as part of standard OS X key management, no other software required).

To minimize my interactions with launchd, I created a single launchd job that calls a bash script. In this way I can simply edit the script without dealing with launchd.

Here's the launchd file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>com.mycron.hourly</string>

  <key>ProgramArguments</key>
  <array>
    <string>/Users/john/bin/cron.hourly</string>
  </array>

  <key>Nice</key>
  <integer>1</integer>

  <key>StartInterval</key>
  <integer>3600</integer> <!-- start every X seconds -->

  <key>RunAtLoad</key>
  <true/>
</dict>
</plist>

I saved the file to ~/Library/LaunchAgents/com.mycron.hourly.plist, and then loaded it with:

launchctl load ~/Library/LaunchAgents/com.mycron.hourly.plist

Once loaded, it will run right away and then again every 60 minutes.

If you follow the same procedure, you'll want to change the `ProgramArguments' string with the right path to your script.

I was curious about the same problem. After reviewing the source code, I found in iTerm2 v1.0.0.20111020 is hard-coded to open a new session as a tab if a session already exists, when it receives nearly any "launch this URL with a handler" command.

My Xcode and Objective-C skills are still rather weak, but if you want to give it a shot I believe the problem is related to the source file iTermController.m. On lines 789 to 870 the launchBookmark:withURL method has the following code:

// Where do we execute this command?
BOOL toggle = NO;
if (theTerm == nil) {
    [iTermController switchToSpaceInBookmark:aDict];
    term = [[[PseudoTerminal alloc] initWithSmartLayout:YES
                                             windowType:[aDict objectForKey:KEY_WINDOW_TYPE] ? [[aDict objectForKey:KEY_WINDOW_TYPE] intValue] : WINDOW_TYPE_NORMAL
                                                 screen:[aDict objectForKey:KEY_SCREEN] ? [[aDict objectForKey:KEY_SCREEN] intValue] : -1] autorelease];
    [self addInTerminals: term];
    toggle = [term windowType] == WINDOW_TYPE_FULL_SCREEN;
} else {
    term = theTerm;
}

id result = [term addNewSession: aDict withURL: url];

I suspect that when theTerm == nil, addNewSession works as expected by launching a new window, since one is currently not running. Perhaps you can modify the code to force the first block to always run, regardless of theTerm's contents.

I hope this helps!! .. It may be worth filing a bug report or contacting the author if you're still having problems.
