Improving my fingerprinting (thanks, Scott):
Total number of files that are GPLv2. Sometimes the FSF and GPL strings
are split across lines. This assumes that one of the two strings is all
on one line. Still simplistic, but less so.
Another important disclaimer: a lot of the GPLv2-ONLY files come from
the linux kernel (see the list below). If and when we move to the
U-Boot v2 driver interface, where we will be able to use linux drivers
more easily, the number of GPLv2-ONLY driver files will likely increase.
$ grep -i -l -r 'Free Software Foundation' * | sort > ufsf.txt
$ grep -i -l -r 'General Public License' * | sort > ugpl.txt
$ cat ufsf.txt ugpl.txt | sort -u > ugplv2.txt
$ wc -l ugplv2.txt
4798 ugplv2.txt
$ cat ugplv2.txt | xargs grep 'either version 2' | awk '{print $1}' |
sed 's/:#*//' > ugplv2-or-later.txt
$ wc -l ugplv2-or-later.txt
4539 ugplv2-or-later.txt
$ for file in `cat ugplv2.txt` ; do grep -il 'version 2' $file ; done |
wc -l
4763
Looking for GPLv2 ONLY files (has some false positives):
$ comm -23 ugplv2.txt ugplv2-or-later.txt > ugplv2-only.txt
After reviewing the files, I come up with 233 GPLv2-only files:
$ wc -l ugplv2-only.txt
233 ugplv2-only.txt
$ cat ugplv2-only.txt
