Top Forums Shell Programming and Scripting Script to find & replace a multiple lines string across multiple php files and subdirectories Post 302604196 by agama on Saturday 3rd of March 2012 03:14:00 PM

Is the block of code the only block that starts <?php and finishes ?>? I suspect that maybe there are other blocks that start and end this way, but on the off chance that this will be the only block like this, then this sed should work:

Code:
sed '/<?php/,/?>/d'  "$file-" >"$file"

It deletes all lines between the starting line with "<?php" and the ending "?>" line as it reads the file. The updated file is written to $file.

If you can use this sed, just replace it in the earlier example.

If there are more than one php blocks of code, then you'll need to find a unique string inside the block that you want to delete. Change the one line in the script below that has "/enter your nickname/" to contain the unique string from the block of code and it should find and delete the lines containing the string.

Code:
#!/usr/bin/env ksh

cd /directory/path/where/you/want/to/start
find . -name "*.php" | while read file
do
    echo "munging: $file"             # nice to see progress as it works
    mv "$file" "$file-"      # back it up
    awk '     # read the file and delete the block of php code
    /<?php/ { drop = idx = 0; snarf = 1; }  # start of a block; start buffering

    /?>/ {                  # end of a block
        if( ! drop )        # magic string not found -- show this block
        {
            for( i = 0; i < idx; i++ )
                printf( "%s\n", buffer[i] );
            printf( "%s\n", $0 );
        }

        snarf = 0;          # turn off buffering
        next;
    }

    ### change the string between the slants to be something unique to the block you wish to delete. 
    /enter your nickname/ { drop = 1; }    # magic string found, drop if we are in a php block

    snarf {                 # if buffering, hold the record until end of block reached.
        buffer[idx++] = $0;
        next;
    }

    { print; }              # not buffering, just print the record.
    '  "$file-" >"$file"
    if (( $? > 0 ))            # handle failure by putting the file back in place
    then
        echo "edit of $file failed" >&2
        mv "$file-" "$file"             # restore original
    else
        rm "$file-"               # worked, delete backup 
    fi
done



Hope this helps get you going.

getopt - Gets options from the command line argument list

SYNOPSIS
array getopt (string $options, [array $longopts]) DESCRIPTION
Parses options passed to the script. PARAMETERS
o $options - Each character in this string will be used as option characters and matched against options passed to the script starting with a single hyphen ( -). For example, an option string "x" recognizes an option -x. Only a-z, A-Z and 0-9 are allowed. o $longopts - An array of options. Each element in this array will be used as option strings and matched against options passed to the script starting with two hyphens ( --). For example, an longopts element "opt" recognizes an option --opt. The $options parameter may contain the following elements: oIndividual characters (do not accept values) oCharacters followed by a colon (parameter requires value) oCharacters followed by two colons (optional value) Option values are the first argument after the string. If a value is required, it does not matter whether the value has leading white space or not. See note. Note Optional values do not accept " " (space) as a separator. Note The format for the $options and $longopts is almost the same, the only difference is that $longopts takes an array of options (where each element is the option) whereas $options takes a string (where each character is the option). RETURN VALUES
This function will return an array of option / argument pairs or FALSE on failure. Note The parsing of options will end at the first non-option found, anything that follows is discarded. CHANGELOG
