Why updating a running Linux system is not problematic? @Nils I'm no expert, but if you run out of cache, wouldn't it be written to swap and reread from there? If that was full then some process would probably be blocked before it could take memory away from another process that is already using it. |

Can I configure bash to execute “clear” before every command typed in the console? Just curious: What's you application for this? Except when I'm debugging programs with a lot of output, I usually want to keep as much as possible on the screen to help me keep track of the context I'm working in. |

Which extension to use for text files? (Unix/Linux) Under KDE, dolphin will often appear to use the extension to select an appropriate icon for the file and sometimes the program that displays it. As others have noted, this is dolphin just trying to be helpful in an ambiguous situation, not some rule or convention in Linux. |

Can I configure bash to execute “clear” before every command typed in the console? Gilles: I pasted the above into a konsole terminal and the output from each command I subsequently entered got cleared before I could read it. Am I missing something? Also, what happens for this (and the other answer below) if I invoke a multi-line bash script where more than one line (or any line other than the last one) generates interesting output? |

Bash: What does “>|” do? As you point out, it is an io redirection rather than a pipe, but you don't address the use of | which is what confused the OP. I didn't recognize this usage either as pointed out by @D_Bye. |

File is mysteriously empty. Options to recover? Look in ~/.openoffice.org/3/user/backup/ or ~/.libreoffice.org/3/user/backup/ I wrote a script to clear these directories so that sensitive things I deleted weren't still there. |

File is mysteriously empty. Options to recover? @Tim I tried areca about a year ago. It was lovely in theory, but when I ran into problems, there was very little support on the forum and I gave up. Is the user community more lively now? |

Make `rm` move to trash Do whatever you want such as the solutions outlined in the answers below, but don't name it rm. As pointed out by others, renaming/repurposing standard commands leaves you vulnerable when you habitually try to use them on other systems, but it also will cause problems for anyone else (perhaps assisting you) using your system/account when unexpected results occur. |

Can I restrict a user to use special programs? I'm not adding this as an answer because I haven't tried it in a long time, but you can change the user's login shell (in /etc/passwd, I believe) to run an arbitrary command or script instead of the default that allows them full normal user access. You just have to test your command/script to make sure the user can't break out of it. |

How to do integer & float calculations, in bash or other languages? As a variation on the bc approach, I added the following function (that I found on stackexchange somewhere) to my .bashrc file. I can just enter calc 2+3 and get 5. ## Command line calculator
calc () {
bc -l <<< "$@"
}

In what order do piped commands run? And what's cool about this example is that when head gets the one line it needs, it terminates and when grep notices this, it also terminates without doing a bunch of further work for nothing. |

Locate enscript reported non-printable chars Found another clue here. The trick is running the files through hexdump first and searching the output. Also found some things about using echo with an unescaped $ to pass raw data into grep. Bottom line, I'm not sure your original grep was correct. stackoverflow.com/questions/4180081/linux-binary-grep unix.com/shell-programming-scripting/… |
