In many PHP files I have defined the variable $_PATHROOT like this
$_PATHROOT = '../../../../';
And I would to replace it with define():
define('_PATHROOT', '../../../../');
Of course, the value ../../../../ differs from one file to another.
Would it be possible with linux sed command line?
Thanks.
It's definitely possible.
The following command should work for any script (it worked for me on a test file):
sed -ri "s/^[$]_PATHROOT = '(([.][.]\/)+)';$/define('_PATHROOT', '\1');/" FILEPATH
where you replace FILEPATH with the path of the file to be edited.
This command assumes that the line you want to change is exactly
$_PATHROOT = '../../';
except that there may be any positive number of "../"s. Any variations in whitespace will throw it off, so if that varies across files you'll need to modify it.
Credit to Kent for the idea of using [$] instead of a mess of backslashes as $ has special meaning in both bash and sed.
This sed one-liner works for the given example:
sed -r "s/^[$](\w+)(.*);/define('\1'\2);/;s/=/,/"
:
kent$ sed -r "s/^[$](\w+)(.*);/define('\1'\2);/;s/=/,/"<<<"\$_PATHROOT = '../../../../';"
define('_PATHROOT' , '../../../../');
find -type f -name "*.php" -exec sed -i .... Is it possible?
$?$.
