Convert JSON to YAML
Convert JSON to YAML. Note that you'll need to have PyYaml installed.

finding cr-lf files aka dos files with ^M characters
Looking for carriage returns would also identify files with legacy mac line endings. To fix both types: $ perl -i -pe 's/\r\n?/\n/g' $(find . -type f -exec fgrep -l $'\r' "{}" \;)

Working random fact generator
Though without infinite time and knowledge of how the site will be designed in the future this may stop working, it still will serve as a simple straight forward starting point. This uses the observation that the only item marked as strong on the page is the single logical line that includes the italicized fact. If future revisions of the page show failure, or intermittent failure, one may simply alter the above to read. $ wget randomfunfacts.com -O - 2>/dev/null | tee lastfact | grep \ | sed "s;^.*\(.*\).*$;\1;" The file lastfact, can then be examined whenever the command fails.

list current ssh clients

Delete only binary files in a directory
Please note that binary file checking is NOT perfect. So, use it with caution. It does not delete hidden files whose name has a leading '.' character. And it regards an empty file as a binary file.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Find Mac address

Get IPv4 of eth0 for use with scripts
Simple and easy. No regex, no search and replace. Just clean, built-in tools.

validate json
I have this saved as jsonlint chmodded +x and file.js is instead $1, but YMMV

Display EPOCH time in human readable format using AWK.
