Means of trimming files
When editing php files, via the command line, there is a newline character
after the closing ?
Im looking for a command that would trim files, so that I can append it to the
find command.
find ./ -name '*.php' -exec SOME_COMMAND {} \;
Thanks

If you're absolutely sure of the number of characters you're removing from
the end of the file, you could use truncate(1).
Otherwise, you'll probably want sed or perl to check that it's not removing
important characters.

Thanks. I'll see what I can come up with...

Trying to use truncate is not working on my end.
Does anyone see a syntax error with it???
Ran on 5.2.1-RELEASE-p6 FreeBSD.
$ pwd
/usr/home/gsam
$ ls ~/z.php
/home/gsam/z.php
$ truncate -r ~/z.php
usage: truncate [-c] -s [+|-]size[K|M|G] file ...
truncate [-c] -r rfile file ...
I tried $ truncate -r rfile ~/z.php but that didn't work either.

Well is 'rfile' the exact length you want and is it always going to
be exactly a newline character shorter than z.php?
Maybe you want something more like 'truncate -s -1 z.php'
presuming it is always just one newline character at the end.
Do you need to take the character only from the last line of the file or
from any line in the file that has it?
If it is from any line, check out tr(1).
tr -d \n z.php z.php-clean
rm z.php
mv z.php-clean z.php
Otherwise, I would be inclined to break out perl.

Well although I can use a bit of perl within php, trying it via the command
line is a bit of a learning curve, that I try to attempt to master it another
day (after reading all those man pages :) ).
Maybe if someone can suggest a how to page on the net, would be appreciated.
But your suggestion on using 'truncate -s -1 z.php' worked as I would like it.
The scenario Im trying to clean up is, if I were to create a file like this on
the command line -
--
?php
phpinfo();
?
--
is actually
--
?php\n
\n
phpinfo();\n
\n
?\n
--
on the file system. Which is normal.
But Im trying to clean up the files to eliminate the trailing \n from the
file, so that its consistent on the command line, and GUI editors, and to
keep the hard core nuts off my back about having trailing space after the
closing ?
So Ill start using truncate() for now, and start investigating perl.
Thanks

As I was writing the previous email, I thought about combining find with php's
cli interface and came up with this dirty command (all in one line) -
find ./ -name '*.php' -exec php -r '$f = file_get_contents({}); $h =
fopen({}, wb); fwrite($h, trim($f)); fclose($h);' \;
It did the job perfectly.

Now _that's_ using the tools ... and the tools you know to boot!

$ perl -0 -pi -e 's/\n+$//s' *.php
will edit each .php file and replace it too. If you want a backup, then
$ perl -0 -p -i.bak -e 's/\n+$//s' *.php
