UNIX for Dummies Questions & Answers

I would like to display the last 8 characters of the filenames for filenames of different lengths.

I can delete the last 8 characters with sed but dont know how to only show the last 8 characters.

The filenames are something like;

afxH340800340000
afxH30800340021
afxR3080034002122

I have used;

echo $file | sed -e 's/........$//g'

Any help is greatly apprecaited.

Cheers

You can use something like this:

Code:

texto="abcdefghijkl"
tot=`echo $texto | wc -c`
echo $texto | cut -c `expr ${tot} - 8`-

Code:

$ echo "afxH340800340000" | sed -e 's/.*\(.\{8\}\)$/\1/'
00340000

Thanks so much, this worked excellent!
