#host #ip address

Extract columns from tables

…like the ones you get on Wikipedia Each column in the table is tab-delineated when you copy and paste it as plain text. Just change the "$2" to "$ whatever column you want to extract" and this one-liner will tidy up whatever's copied into your clipboard for you.

pbpaste | awk 'BEGIN{ FS="\t";}{print $2}' | pbcopy

#pbpaste #awk #pbcopy #columns

Count occurrences of each word in the paste buffer

Count how many times each word crops up in the paste buffer

pbpaste|perl -pe 's/\W+/\n/g'|awk '{IGNORECASE=1;c[$1]++}END{for(j in c) print j,c[j]}'

#pbpaste #awk #perl #words #count
