Anannd,

Use grep with the -n option to pick out the line number where your number/text occurs in the file.

grep -n abcfile

Then use tail to select from that line to the end of the file

Then use head to select just a few lines from that

Is that enough for you to go on or would you like an example?

Hi everybody,

You can also use the grep -p "uniqueid=1" :
it will give the whole stanza if your file is made of stanzas.

Hope this help
