How to `egrep “mysqli_close” *.php` exclude `*-*.php

To search for files containing “mysqli_close” in all .php files, excluding files with a hyphen in their name (like *-*.php), you can use the find command in combination with grep. Here’s an example command:

find . -type f -name "*.php" ! -name "*-*" -exec grep -E "mysqli_close" {} +

Explanation of the command:

• find .: Start searching from the current directory.
• -type f: Look for files only.
• -name "*.php": Match files with a .php extension.
• ! -name "*-*": Exclude files containing a hyphen in their name.
• -exec: Execute a command on the matched files.
• grep -E "mysqli_close": Use grep with extended regular expressions (-E) to search for “mysqli_close” in the files.
• {}: Placeholder for the matched file name.
• +: Indicate the end of the command to be executed on each file.
