Script to find & replace a multiple lines string across multiple php files and subdirectories
Hey guys. I know pratically 0 about Linux, so could anyone please give me instructions on how to accomplish this ?
The distro is RedHat 4.1.2 and i need to find and replace a multiple lines string in several php files across subdirectories.
So lets say im at root/dir1/dir2/ , when i execute the script it should search and replace a piece of code on php files inside this directory and its subdirectories.
The closest i found i think it was this:
Code:
Paste this into a file ‘renall’ and make it executable (chmod u+x renall): #!/bin/sh
if [ $# -lt 3 ] ; then
echo -e “Wrong number of parameters.”
echo -e “Usage:”
echo -e ” renall ‘filepat’ findstring replacestring\n”
exit 1
fi
#echo $1 $2 $3
for i in `find . -name “$1″ -exec grep -l “$2″ {} \;`
do
mv “$i” “$i.sedsave”
sed “s/$2/$3/g” “$i.sedsave” > “$i”
echo $i
#rm “$i.sedsave”
done
But the string i need to find and replace have multiple lines, so i dont know how to put it in this script.
Also i dont know how to save and execute this script
EDIT: AH and by the way, i need to only DELETE the piece of code from these PHP files, i dont need to replace it with something else...
Could anyone please give me detailed instructions on this ?

I used the following script
cd pathname
for y in `ls *`;
do sed "s/ABCD/DCBA/g" $y > temp; mv temp $y;
done
and it worked fine for finding and replacing strings with names etc. in all files of the given path.

find . -type f -name "*.sql" -print|xargs perl -i -pe 's/pattern/replaced/g'
this is simple logic to find and replace in multiple files & folders
Hope this helps.

I am creating a script to do a find and replace single/multiple lines in a file with any number of lines.
I have written a logic in a script that reads a reference file say "findrep" and populates two variables $FIND and $REPLACE
print $FIND gives

LEARN ABOUT PHP
popen
POPEN(3) 1 POPEN(3)popen - Opens process file pointerSYNOPSIS
resource popen (string $command, string $mode)
DESCRIPTION
Opens a pipe to a process executed by forking the command given by $command.
PARAMETERS
o $command
- The command
o $mode
- The mode
RETURN VALUES
Returns a file pointer identical to that returned by fopen(3), except that it is unidirectional (may only be used for reading or writing)
and must be closed with pclose(3). This pointer may be used with fgets(3), fgetss(3), and fwrite(3). When the mode is 'r', the returned
file pointer equals to the STDOUT of the command, when the mode is 'w', the returned file pointer equals to the STDIN of the command.
If an error occurs, returns FALSE.
EXAMPLES
Example #1
popen(3) example
<?php
$handle = popen("/bin/ls", "r");
?>
If the command to be executed could not be found, a valid resource is returned. This may seem odd, but makes sense; it allows you to
access any error message returned by the shell:
Example #2
popen(3) example
<?php
error_reporting(E_ALL);
/* Add redirection so we can get stderr. */
$handle = popen('/path/to/executable 2>&1', 'r');
echo "'$handle'; " . gettype($handle) . "
";
$read = fread($handle, 2096);
echo $read;
pclose($handle);
?>
NOTES
Note
If you're looking for bi-directional support (two-way), use proc_open(3).
Note
When safe mode is enabled, you can only execute files within the safe_mode_exec_dir. For practical reasons, it is currently not
allowed to have .. components in the path to the executable.
Warning
With safe mode enabled, the command string is escaped with escapeshellcmd(3). Thus, echo y | echo x becomes echo y | echo x.
