Syntax errors in a bash script executed from tcsh So the problem is with single quotes you used to wrap your whole commands. It prevents back-quotes to be replaced with its result. Try this: bash -c "for i in 1 2; do if [ 146 = `echo $numbers | cut -f$i -d' ' ` ]; then echo 'NUM is OK '; fi done" |

Why there are only two user defined signals? @Random832 You're right, I know what you say. But the problem I was thinking about was that what if I ran out of my 31 choices of signals? |

Why there are only two user defined signals? Thanks. In my case I handle SIGUSR1 for reconfiguration. It means when the admin wants to change the configuration of my running process, it changes the config file and sends a SIGUSR1 to my PID (easier to use a pipe here). And I use SIGUSR2 for clean process shutdown. It hadn't got necessary for me to use a signal other than these two, but some runtime features could be implemented by handling other user defined signals! |

Ansi escape code in VIM unfortunately it does not support some escape codes, like high intensity foreground color! |

Ansi escape code in VIM Thanks, it works. I used the v2 version and Text is colored. Maybe I use another script to suppress the ANSI characters (if I don't want to use the conceal patch). |

Using in/out named pipes for a TCP connection @noffle because, as I said, netcat will close whenever one of its network connections closes. If you close the client (which sends a string and receives the same string), netcat server will be closed too. I wrote a server code for myself in this case that forks itself to handle multiple clients and reconnect of clients. |
