Check These Out
This is the SECOND command in a set for five that are needed for a Twitter stream feed.
This command creates variable "b", the so-called "base string" required for oauth in Twitter stream feed requests. (The 256 char limit prevents giving it a better name)
We use five environment variables created by a previous step: id, k1, once, ts and k3.
The five environment variables are created in a separate command, please see my other commands.
For more information on the signature base string, see dev.twitter.com/apps, click on any app (or create a new one) and then go to the "OAuth Tool" tab.
make, find and a lot of other programs can take a lot of time. And can do not. Supppose you write a long, complicated command and wonder if it will be done in 3 seconds or 20 minutes. Just add "R" (without quotes) suffix to it and you can do other things: zsh will inform you when you can see the results.
You can replace zenity with other X Window dialogs program.
This was gotten from http://www.veen.com/jeff/archives/000573.html. The line will grab all the mp3 files on the urls listed in text file sourceurls.txt (one url per line) . A much more complete breakdown of the line can be found at the web site mentioned above.
Sends both stdout and stderr to the pipe which captures the data in the file 'out.test' and sends to stdout of tee (likely /dev/tty unless redirected). Works on Bourne, Korn and Bash shells.
This command runs your shell script in the background with no output of any kind, and it will remain running even after you logout.
If you are doing some tests which require reboots (e. g. startup skripts, kernel module parameters, ...), this is very time intensive, if you have got a hardware with a long pre-boot phase due to hardware checks.
At this time, kexec can help, which only restarts the kernel with all related stuff.
First the kernel to be started is loaded, then kexec -e jumps up to start it.
Is as hard as a reboot -f, but several times faster (e. g. 1 Minute instead of 12 on some servers here).
Shows which packages from the official repositories (not aur) have updates available. For most accurate output, the mirrors and package lists should be up to date.
Alternatively,
$ ls -F | grep /\$
but will break on directories containing newlines. Or the safe, POSIX sh way (but will miss dotfiles):
$ for i in *; do test -d "./$i" && printf "%s\n" "$i"; done
First argument: string to put a box around.
Second argument: character to use for box (default is '=')
Same as command #4962, cleaned up, shortened, and more efficient. Now a ' * ' can be used as the box character, and the variables get unset so they don't mess with anything else you might have.
They marked c++ as a function for this command, but I'm not sure why. Must be a bug.
