Matching sequence of numbers in URL after specific text - regex

Question

I'm trying to match a sequence of numbers that comes after "job=" while ignoring what comes before it and after it like "list.php?job=11534&name"
Below I've posted what I have so far, which seems to have no affect on the URL.
Also, will [L] only stop the rewrite engine if the rule matches or no matter what?
Thanks in advance for your help.
Current Rule:
RewriteEngine On
RewriteCond %{QUERY_STRING} (?:^|&)job=([^&]+)
RewriteRule ^([0-9]+)$ /positions/job/$1 [L]
# Removes index.php from ExpressionEngine URLs
RewriteCond $1 !\.(gif|jpe?g|png)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?/$1 [L]

Answer 1

RewriteRule ^([0-9]+)$ will match requests that contain only numbers (/4666), this regular expression should be placed in the RewriteCond instead, %1 will refer to it, and the trailing ? in the rewriterule exclude the query string from the new url (is that what you want?).
L will stop the rewrite engine for the current url only if the rule matches.
RewriteCond %{QUERY_STRING} (?:^|&)job=([0-9]+)
RewriteRule ^.+$ /positions/job/%1? [L]
if you want to redirect the user to the new URL, add R to the rewriterule options ([L,R=301]),
be careful that these directives will redirect any url where the query string matches job=([0-9]+) to the new url, if you wanna to restrict the redirection to certain requests(like /folder/list.php?job=qsd&name=qsd), be sure to include them in the rewrite rule, so the directives would be :
RewriteCond %{QUERY_STRING} (?:^|&)job=([0-9]+)
RewriteRule ^folder/list\.php$ /positions/job/%1? [L]
