I've been using Linux since the late 90's, and have had a career involving Solaris, a tiny bit of Irix, and plenty of Linux - mostly operating at the shell scripting and application level.
I currently use XUbuntu for most development, an OSX Desktop on a home PC, and various server setups including RH, FC and Debian.

Find out if the OS is running in a virtual environment nice - this works on virtual box: dmesg | grep -i vbox - ACPI: RSDP 000e0000 00024 (v02 VBOX ) |

ERROR:While Updating You appear to be switching from 32bit to 64bit packages. I'd certainly be looking to do a fresh install and migrate my configuration to it than try and upgrade through to that. |

Why does a desktop launcher does not start my app, while command line does? It is possible that the script is relying on other aspects of your shell environment that is different from when it is run via the desktop launcher. Perhaps you can add a line near the top to dump the env into a file, and then diff them? |

Tmpfs only with RAM +1 to h3rrmiller - I've seen a ramfs setup consume all available memory until a machine dies. tmpfs is more appropriate. Also there is little point swapping to ram - why swap at all? |

Install only a few GNU coreutils? Not so much an answer as a pointer to an idea - buildroot normally sets up only a subset of coreutils, and if you have a smallish subset, you might want to consider busybox with the relevant tools. |

Doing two things with output from a command @dubiousjim That semicolon is correct - the pipe works, but the semi colon better expresses what is intended. |

Why do newlines mess up my while condition? You could probably get the multiline style you want using a subshell - start with an opening paren on the first line and end it before the do. You should also be able to use a bash function here too. |

How can I get bash to exit on backtick failure in a similar way to pipefail? Thanks for this. An experience I had was that some errors caught in a later version of bash, were ignored in earlier versions with set -e. My intent here is to harden scripts to the extent that any non-handled error return/failure condition will cause a script to exit. This is in a legacy system which has been known to produce garbage output files and a "0" happy exit code after a half an hour of chaos with the wrong env - unless you were watching output like a hawk (and not all of the errors are on stderr, some are on stdout, and some parts are /dev/null'd), you just don't know. |

How can I get bash to exit on backtick failure in a similar way to pipefail? Not sure about the read trick, attempting it lead to the variable not being bound. I think this may be because the other side of the pipe is effectively a subshell, name won't be available. |
