[ale] Determining a scripts language?

[Jim Kinney]

the file command will give you details about what type of file. That is
an easy way to determine if it's a script file.
for myfile in $( find . -type f | head -n 10000 ); do file ${myfile} |
egrep -i script| egrep -v makefile; done 
./rpmbuild/BUILD/cinelerra/libmpeg3/make_package: POSIX shell script,
ASCII text executable
./rpmbuild/BUILD/cinelerra/libmpeg3/configure: POSIX shell script,
ASCII text executable
./rpmbuild/BUILD/cinelerra/libmpeg3/mpeg3cat: POSIX shell script, ASCII
text executable, with very long lines
./rpmbuild/BUILD/cinelerra/libmpeg3/make_rpm: POSIX shell script, ASCII
text executable
./rpmbuild/BUILD/cinelerra/libmpeg3/mpeg3toc: POSIX shell script, ASCII
text executable, with very long lines
./rpmbuild/BUILD/cinelerra/libmpeg3/mpeg3dump: POSIX shell script,
ASCII text executable, with very long lines
./rpmbuild/BUILD/cinelerra/config.sub: POSIX shell script, ASCII text
executable
./rpmbuild/BUILD/cinelerra/aclocal.m4: M4 macro processor script, ASCII
text, with very long lines
./rpmbuild/BUILD/cinelerra/libtool: POSIX shell script, ASCII text
executable
./rpmbuild/BUILD/cinelerra/cinelerra/gen-feather-h: Perl script, ASCII
text executable
Now to pull out the actual files
for myfile in $( find . -type f | head -n 10000 )  # I added the |head
-n 10000 to cut down of the file processing
  do myfullfile=$(file ${myfile} | egrep -i script| egrep -v makefile |
awk -F ':' '{print $1}') 
    mybasefile=$(basename ${myfullfile})
    mydirname=$(dirname ${myfullfile})
    mynewbase=$(echo ${mybasefile} | awk -F '.' '{$NF=""; print $0}' |
sed 's/ \+$/.txt/'
    cp ${myfullfile} ${mydirname}/${mynewbase}
done
I feel like the sed to scrap the trailing space for the .txt is a
kludge but the funky awk print adds the space.

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
