Catches .swp, .swo, .swn, etc. If you have access to lsof, it'll give you more compressed output and show you the associated terminals (e.g., pts/5, which you could then use 'w' to figure out where it's originating from): lsof | grep '\.sw.$' If you have swp files turned off, you can do something like: ps x | grep '[g,v]im', but it won't tell you about files open in buffers, via :e [file].

This executes faster than cygstart.exe I put this in a script and added it to my path: cat `which explore.sh` #!/bin/bash if [ $# -eq 0 ]; then explorer.exe $( cygpath `pwd` -w ) & else explorer.exe $( cygpath $1 -w ) & fi; Using the script you just type explore.sh file_or_executable Note: you can do this for any file that has an associated executable in the windows registry. This is quite handy if you want to open pictures or movies from xterm. Show Sample Output

Change open-command and type to suit your needs. One example would be to open the last .jpg file with Eye Of Gnome: eog $(ls -rt *.jpg | tail -n 1)

Check trough unix sockets if tcp port is open or close Show Sample Output

netstat will list all open ports on the system, unix sockets, tcp sockets and udp sockets. the t flag limits to tcp ports the l flag limits to listening ports and the n flag disables the translation of port to service ( ie :25 displayed instead of :smtp ). then grep for the port you are interested in preceeded by a colon. Show Sample Output

Using netcat (nc) 25 can be replaced with the friendly value (smtp). Check error code for result or use -v option to echo output nc -z localhost smtp && echo open || echo closed nc -zv host protocol Show Sample Output
