This command is a more flexible than my previous submission. It will work with spaces however suuuuper hacky and ugly. Source: http://www.unix.com/shell-programming-scripting/146173-find-rename-files-using-find-mv-sed.html Show Sample Output

flip shell history with PG UP/PG DOWN like with arrows. just type ss and PG UP and see all ssh commands, type ls and PG DOWN - see all ls commands. need to uncomment two options in /etc/inputrc: "\e[5~": history-search-backward "\e[6~": history-search-forward hack found: http://broddlit.wordpress.com/2008/04/12/making-the-bash-history-a-better-place/

Sometimes, you don't want to just replace the spaces in the current folder, but through the whole folder tree - such as your whole music collection, perhaps. Or maybe you want to do some other renaming operation throughout a tree - this command's useful for that, too. To rename stuff through a whole directory tree, you might expect this to work: for a in `find . -name '* *'`;do mv -i "$a" ${a// /_};done No such luck. The "for" command will split its parameters on spaces unless the spaces are escaped, so given a file "foo bar", the above would not try to move the file "foo bar" to "foo_bar" but rather the file "foo" to "foo", and the file "bar" to "bar". Instead, find's -execdir and -depth arguments need to be used, to set a variable to the filename, and rename files within the directory before we rename the directory. It has to be -execdir and won't work with just -exec - that would try to rename "foo bar/baz quux" to "foo_bar/baz_quux" in one step, rather than going into "foo bar/", changing "baz quux" to "baz_quux", then stepping out and changing "foo bar/" into "foo_bar/". To rename just files, or just directories, you can put "-type f" or "-type d" after the "-depth" param. You could probably safely replace the "mv" part of the line with a "rename" command, like rename 'y/ /_/' *, but I haven't tried, since that's way less portable.

Run "ps -x" (process status) in the background every hour (in this example). The outputs of both "nohup" and "ps -x" are sent to the e-mail (instead of nohup.out and stdout and stderr). If you like it, replace "ps -x" by the command of your choice, replace 3600 (1 hour) by the period of your choice. You can run the command in the loop any time by killing the sleep process. For example ps -x 2925 ? S 0:00.00 sh -c unzip E.zip >/dev/null 2>&1 11288 ? O 0:00.00 unzip E.zip 25428 ? I 0:00.00 sleep 3600 14346 pts/42- I 0:00.01 bash -c while true; do ps -x | mail (...); sleep 3600; done 643 pts/66 Ss 0:00.03 -bash 14124 pts/66 O+ 0:00.00 ps -x kill 25428 You have mail in /mail/(...)

For easy portability you can include you service account blobs directly to your rclone config. So it generate a rclone config like the following: [dst977] type = drive scope = drive service_account_credentials = {"type":"service_account","project_id":"saf-ju66hcgi8qf8zidhvfww4oxwe7","private[.................] } Show Sample Output

This function displays the latest comic from xkcd.com. One of the best things about xkcd is the title text when you hover over the comic, so this function also displays that after you close the comic. To get a random xkcd comic use the following: xkcdrandom() { wget -qO- http://dynamic.xkcd.com/comic/random | sed -n 's#^<img src="\(http://imgs.[^"]\+\)"\s\+title="\(.\+\?\)"\salt.\+$#eog "\1"\necho '"'\2'#p" | bash; } These are just a bit shorter than the ones eigthmillion wrote, however his version didn't work as expected on my laptop for some reason (I got the title-tag first), so these build a command which is executed by bash.

An easy way to send all directories to a bash script, it makes it recursive

find pictures recursively in a specified folder and renames the file name to originalname_containingfoldername.jpg

So I use OSX and don't have the shuf command. This is what I could come up with. This command assumes /usr/share/dict/words does not surpass 137,817,948 lines and line selection is NOT uniformly random. Show Sample Output

No need to install additional packages eg: say hello For multiword say how+are+you

When a large maven release goes wrong, by deploying just some of the artifacts letting others behind, some projects got wrong SNAPSHOT versions. This command comes to help! Tip: replace sed's regex by your version numbers

Can use minute - m, hour - h Eg: sudo bash -c "sleep 2h; pm-hibernate" will hibernate the system after 2hours.

Change current working directory with root permissions. Place this snippet in your .bashrc to add a new "sudocd" command: function sudocd { sudo bash -c "cd $1;bash" } Usage: sudocd DIRECTORY Please note that if you will use this command to cd into directories with the permissions allowing only root to be in them, you will have to use sudo as a prefix to every command that changes/does something in that directory (yes, even ls).

Single file archives nested in subdirectories. After extracting them, you'll have the file (e.g. file.ext) and the archive (e.g. file.ext.nco) side by side. Sometimes you'll only have the archive (if you didn't extract them, or if there was an error during extraction). Only delete the archive if the single file is present in the same directory.
