You can download the file and get its size. But we can do better. Use curl to get only the response header using the -I option. In the response header look for Content-Length: which will be followed by the size of the file in bytes. $ URL=”http://api.twitter.com/1/statuses/public_timeline.json” $ curl -sI $URL | grep -i Content-Length … Read more
Print lines between PAT1 and PAT2 $ awk ‘/PAT1/,/PAT2/’ file PAT1 3 – first block 4 PAT2 PAT1 7 – second block PAT2 PAT1 10 – third block Or, using variables: awk ‘/PAT1/{flag=1} flag; /PAT2/{flag=0}’ file How does this work? /PAT1/ matches lines having this text, as well as /PAT2/ does. /PAT1/{flag=1} sets the flag … Read more
