Question

I have searched and not found a solution so sorry if this has been answered before, I’m not great at shell.

I’m trying to do a recursive search and replace in all files via SSH.

So far I’ve got this:

find . -type f | xargs -d "\n" perl -pi -e 's/$this->helper('catalog/product')->getPriceHtml/$this->getPriceHtml/g'

I’m trying to replace this:

$this->helper('catalog/product')->getPriceHtml

with this:

$this->getPriceHtml

But I think its not working because of the slashes and single quotes. I have tried escaping these with \ but to no avail, any ideas?

Answer 1

An alternate delimiter for the s operator could be used to avoid picket fences. $this will be considered to be a variable unless the $ is escaped. The parentheses have to be escaped as well. Else they form a capture group. Since it is a one-liner and quotes have been exhausted, single-quotes have been encoded using hexadecimal escapes. The following should work:

s{\$this->helper\(\x{27}catalog/product\x{27}\)->getPriceHtml}{\$this->getPriceHtml}g;

Or:

s{(?<=\$this)->helper\(\x{27}catalog/product\x{27}\)(?=->getPriceHtml)}{}g;
