Return the creation date of a file on ext2, 3, 4 filesystems, because stat command won't show it.
Useful on ubuntu, debian, and else
Gives you a list for all installed chrome (chromium) extensions with URL to the page of the extension.
With this you can easy add a new Bookmark folder called "extensions" add every URL to that folder, so it will be synced and you can access the names from every computer you are logged in.

mysql -uroot -p'passwd' database <
Say you're started "xzcat bigdata.xz | complicated-processing-program >summary" an hour ago, and you of course forgot to enable progress output (you could've just put "awk 'NR%1000==0{print NR>"/dev/stderr"}{print}'" in the pipeline but it's too late for that now). But you really want some idea of how far along your program is. Then you can run the above command to see how many % along xzcat is in reading the file.
Note that this is for the GNU/Linux version of lsof; the one found on e.g. Darwin has slightly different output so the awk part may need some tweaks.

Shows all block devices in a tree with descruptions of what they are.
Will use variable value (for variable $my_dir, in this case), an assign a default value if there is none.
This is a beginning script. You can create a file with > filename. You can also use diff to compare output run at different times to verify no change in your files. I apologize in advance if this is too simple. For some it should be a start.
