UNIX for Dummies Questions & Answers

I`m having a output shown below,

CFR 235,BBC DM-2 ALL
CFR 111,BBC DM-2 ALL
CFR 333,BBC DM-2 ALL

from the above Output i want to use 235,111,333 as input for other purpose.
these no always change every time i run script.so please suggest me the way i could do it with example,i have tried grep command but as no changes this commands fail the grep right number.also tell the way i can use these number as input for other command.

for example

Code:

echo "CFR 235,BBC DM-2 ALL
CFR 111,BBC DM-2 ALL
CFR 333,BBC DM-2 ALL" | grep -Eo "[0-9]{3}" | sort -g
111
235
333

One way:

Code:

egrep -o "[0-9]{3}" in.file

Another:

Code:

cat in.file | awk -F "[ ,]" '{print $2}'

Code:

sed 's/.* \([0-9]*\),.*/\1/' < file

awk '{ print $2 }' | awk -F, '{ print $1 }' | tr '\n' ','

Dear friend ,

You can use the following way also, to get the number only

The input file contain the following content

CFR 235,BBC DM-2 ALL
CFR 111,BBC DM-2 ALL
CFR 333,BBC DM-2 ALL

Code:

 
cut -b 5-7 file

Here "-b" is used to extract the data from the file using the bytes. Here I use the bytes between the 5 to 7
