Listen Digitally Imported Radio from CLI (without premium!)

This commands does just two things: fakes user agent (the one was taken from recent Android app) and sends the (possibly) listener ID (it can be any - I put "1" here because it works like a charm - after the name of stream ?1 as you can see).

Look for the list of stations here: http://pub7.di.fm

Remove specific versions of old kernels (Ubuntu/Debian)

If, for example, you want to remove all kernels and headers but the last three versions, you can't use one of that magic all-in-one "remove old stuff" commands.

With this simple but elegant command you can remove a range of versions, or a list of versions with e.g. {14,16,20}.

Get AWS temporary credentials ready to export based on a MFA virtual appliance

You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token.

This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use:

`awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'`

You must adapt the command line to include:

* $MFA_IDis ARN of the virtual MFA or serial number of the physical one

* TTL for the credentials

List latest 5 modified files recursively

The output format is given by the -printf parameter:

%T@ = modify time in seconds since Jan. 1, 1970, 00:00 GMT, with fractional part. Mandatory, hidden in the end.

%TY-%Tm-%Td %TH:%TM:%.2TS = modify time as YYYY-MM-DD HH:MM:SS. Optional.

%p = file path

Refer to http://linux.die.net/man/1/find for more about -printf formatting.

------------------------

sort -nr = sort numerically and reverse (higher values - most recent timestamp - first)

head -n 5 = get only 5 first lines (change 5 to whatever you want)

cut -f2- -d" " = trim first field (timestamp, used only for sorting)

------------------------

Very useful for building scripts for detecting malicious files upload and malware injections.

Safe Russian Roulette (only echo, don't delete files)

Shows "Bang!" in a chance of 1 out of 6, like in the original game with the gun (spin every round). Otherwise, echoes "Click...". If feeling brave you can also do:

[ $[ $RANDOM % 6 ] == 0 ] && echo 'Bang!' && a really killer command || echo 'Click...'

Easy file sharing from the command line using transfer.sh

Requires:

curl

xsel

access to the internet(http://transfer.sh)

This is an alias utilizing the transfer.sh service to make sharing files easier from the command line. I have modified the alias provided by transfer.sh to use xsel to copy the resulting URL to the clipboard.

The full modified alias is as follows since commandlinefu only allows 255 characters:

transfer() { if [ $# -eq 0 ]; then echo "No arguments specified. Usage:\necho transfer /tmp/test.md\ncat /tmp/test.md | transfer test.md"; return 1; fi if tty -s; then basefile=$(basename "$1" | sed -e 's/[^a-zA-Z0-9._-]/-/g'); curl --progress-bar --upload-file "$1" "https://transfer.sh/$basefile" |xsel --clipboard; else curl --progress-bar --upload-file "-" "https://transfer.sh/$1" |xsel --clipboard ; fi; xsel --clipboard; }

Recursively remove directory with many files quickly

rsync'ing an empty directory over a directory to be deleted recursively is much faster than using rm -rf, for various reasons. Relevant only for directories with really a lot of files.
