find files between specific date/times and move them to another folder

touch -t 201208211200 first ; touch -t 201208220100 last ; creates 2 files: first & last, with timestamps that the find command should look between: 201208211200 = 2012-08-21 12:00 201208220100 = 2012-08-22 01:00 then we run find command with "-newer" switch, that finds by comparing timestamp against a reference file: find /path/to/files/ -newer first ! -newer last meaning: find any files in /path/to/files that are newer than file "first" and not newer than file "last" pipe the output of this find command through xargs to a move command: | xargs -ifile mv -fv file /path/to/destination/ and finally, remove the reference files we created for this operation: rm first; rm last;

Debug pytest failures in the terminal

pudb is an ncurses debugger. This command will allow interactive debugging of test failures in pytest using pudb.

File rotation without rename command

Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.

urldecoding

$ echo "http%3A%2F%2Fwww.google.com" | sed -e's/%$[0-9A-F][0-9A-F]$/\\\\\x\1/g' | xargs echo -e http://www.google.com $ Works under bash on linux. just alter the '-e' option to its corresponding equivalence in your system to execute escape characters correctly.

Simple server which listens on a port and prints out received data

Sometimes you need a simple server which listens on a port and prints out received data. Example: Consider you want to know, which data is posted by a homepage to a remote script without analysing the html code! A simple way to do this is to save the page to your computer, substitude all action="address" with action="localhost:portnumber", run 'ncat -l portnumber' and open the edited page with your browser. If you then submit the form, ncat will print out the http-protocol with all the posted data.

Set file access control lists

The file myfile is owned by tom and has read and write permissions for tom. Group and other permissions are empty which make myfile readable and writable only by tom. setfacl enables user tom to give read permission to user john only. The command 'ls -l' shows a '+' sign telling us that file access control list has been setup for myfile.

List your installed Chromium extensions (with url to each page)

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. ------------------------------------------------------------------------------------------------------------------ Only tested with chromium, for chrome you maybe have to change the find $PATH.

get header and footer of file for use with scalpel file carving

file carving helps if you know where the file you are looking for starts and ends. It's also an easy way to get data and catalog them for future use with forensic tools like scalpel.

Detect illegal access to kernel space, potentially useful for Meltdown detection

Based on capsule8 agent examples, not rigorously tested

sed : using colons as separators instead of forward slashes

Having to escape forwardslashes when using sed can be a pain. However, it's possible to instead of using / as the separator to use : . I found this by trying to substitute $PWD into my pattern, like so $ sed "s/~.*/$PWD/" file.txt Of course, $PWD will expand to a character string that begins with a / , which will make sed spit out an error such as "sed: -e expression #1, char 8: unknown option to `s'". So simply changing it to $ sed "s:~.*:$PWD:" file.txt did the trick.

Converts uppercase chars in a string to lowercase

Another alternative is to define a function: lower() { echo ${@,,} } lower StrinG
