Hi @PedroSFreitas,

Unix is a tool builder's culture. Think of Lego bricks. Explore how the following bricks are combined.

grep -r '  *$' *
grep -rl '  *$' *
vi -o `grep -rl '  *$' *`  ;# <Esc>:qa to get out of vi
find * -name '*.py' -print
find * -name '*.py' -exec grep '  *$' {} \;
find * -name '*.py' -exec grep -l '  *$' {} \;
find * -name '*.py' -exec grep -l '  *$' {} \; | while read f; do t=`mktemp`; echo sed -e 's/  *$//' "$f" "$t";echo mv -f "$t" "$f";done
find * -name '*.py' -exec grep -l '  *$' {} \; | while read f; do t=`mktemp`; sed -e 's/  *$//' <"$f" >"$t";mv -f "$t" "$f";done

Unix is a tool builder's culture.

Not sure, but I believe I read a similar definition of Unix on K&R. Or maybe on another book.

The two following books are excellent.

• The UNIX Programming Environment This is a tutorial for doing things the unix way, even though some of the commands are irrelevant now.
• The Unix Philosophy by Mike Gancarz great book for explaining the philosophy. It is not a tutorial. There is a newer version called Linux and the Unix Philosophy: Mike Gancarz. I have not read the newer version.

I do not know if any of the above books say "Unix is a tool builder's culture", but they sure live it.
