Extract a string from file
Below are the content of my file and i need to extract the 6 digit numbers after the word barcode, how can i do this?

for example i need to extract 004119,004275,004030 to a new file.
Code:
Logically move media ID 004119 (barcode 004119) from standalone to slot 18.
Logically move media ID 004275 (barcode 004275) from standalone to slot 34.
Logically move media ID 004030 (barcode 004030) from standalone to slot 37.

Maybe you didn't post everything we should see!

Code:

sed -n "/barcode/s/.*barcode \(.\{6\}\).*/\1/p" infile

Or

Code:
awk '/barcode/ {print substr($7,1,6) }' oldfile > newfile

Or based on your unpdated input:

Code:

sed -n "/^Log.*barcode/s/.*barcode \(.\{6\}\).*/\1/p" infile

Or

Code:
awk '/^Log.*barcode/ {print substr($7,1,6) }' oldfile > newfile
