Note that this man page is regarding date version ‘date (GNU coreutils) 8.4’, your mileage may vary when using other versions.

I’m going to expand this section to include examples of every entry from the man page. Note that some examples include additional commands to demonstrate the information we are working with.

Just a starter page that will grow as I find useful awk commands to share.

Convert Linux .txt to Windows .txt
Replace the end of a line with a carriage. Useful for converting .txt files from Linux to Windows.

awk 'sub("$", "\r")' linuxfile.txt > windowsfile.txt

Convert Windows .txt to Linux .txt
And the reverse. Useful for converting .txt files from Windows to Linux.

awk '{ sub("\r$", ""); print }' windowsfile.txt> linuxfile.txt

This will be a growing list as I find commands I need…

Find files of .ext that are 0 bytes and rm them.

find . -name "*.ext" -size 0 -exec rm {} \;
