Is there a way to pipe the diff output into
patch? The -i parameter is for specifying a diff file, but I just want to do it more dynamically, since I will be updating regularly against a directory that changes frequently.
For instacne, something along the lines of
patch -b | diff -Nub . /current-files
The man file says
-i patchfile or --input=patchfile Read the patch from patchfile. If patchfile is -, read from standard input, the default.
But when I try it, I just see the output of the diff on the screen, with no changes applied:
testb $> ls file.txt testb $> patch -i - | diff -Nub . ../testa diff -Nub ./file.txt ../testa/file.txt --- ./file.txt 2011-07-12 09:40:08.195467000 -0400 +++ ../testa/file.txt 2011-07-12 09:39:11.181666500 -0400 @@ -1,9 +1,7 @@ ijaosdfji jaiosdfjio jklasdkml -asdkml -s;lnk -lsadjkl -asdfas -asdf +klasdkml +nas;lnk +jklsadjkl diff -Nub ./file2.txt ../testa/file2.txt --- ./file2.txt 1969-12-31 19:00:00.000000000 -0500 +++ ../testa/file2.txt 2011-07-12 09:39:44.196235000 -0400 @@ -0,0 +1,6 @@ +aljksdf +jklasdflkjlknm +nksalk; +klaskl; +ioasjdoiaj +lkmasd'lkm testb $> ls file.txt
