Over the last few months, I have re-discovered some unix commands (it’s been such a long time)
- Eliminate duplicate lines from a file
#sort -u filename > filename.new
- List all lines that do not match a condition
#grep -v ajsk filename
- Copy contents of two files to one
#cat file1 file2 > file3
- Append output of a command to a file
#cat file1 >> file2
