Thanks!...
Current scenario, I launch a process that forks, and after a while it aborts(). The thing is that both the fork and the original process print to the shell, but after the original one dies, the shell "returns" to the prompt. I'd like to avoid the shell returning to the prompt and keep as if the process didn't die, having the child handle...

I'm trying to use someone else's [c] code that controls a linux shell over a wireless usb device. It fopen-s files "IReadFromBash" and "IWriteToBash" in the current dir to communicate. It comes with no notes but obviously expects a special file to already exist to facilitate this, and segfaults without them. Is there some obvious way to ...

Using Perforce, I'd like to be able to reject submits which contain files with Windows line endings (\r\n IIRC, maybe just \r anywhere as really we only want files with Unix line endings). Rather than dos2unix incoming files or similar, to help track down instances where users attempt to submit files with Windows line endings, I'd like ...
After installing a full version of Cygwin, I open up the MinTTY shell and I like the green on black. However, when I do an 'ls', I get a dark blue for directories. It's not very readable. I found that the LS_COLORS environment variable controls the output of ls. Here is my current default: no=00:fi=00:di=00;34:ln=00;36:pi=40;33:so=...

I recently made the insanely long overdue switch from tcsh to bash. The only thing I miss is tcsh's ESC-p feature: Start typing a command and then hit ESC-p (I actually found the equivalent ctrl-[p easier to type) and it jumps to the most recent command in your history that starts with what you've typed so far. Perhaps the best answer i...
