Find and replace a string in multiple files

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.

I'm trying to replace a string which consists of path (location of file)

say instead of ABCD i have to replace c:/mydocuments/pictures to
d:/mypics/personal , as metacharacters wont be searched in unix this script is failing to replace the string which has a path in it.

now my script is


cd pathname
for y in `ls *`;
do sed "s/'c:/mydocuments/pictures'/'d:/mypics/personal'/g" $y > temp; mv temp $y;
done





i tired giving the path in single quotes and double quotes, but i see error

sed: command garbled: s/'c:/mydocuments/pictures'/'d:/mypics/personal'/g



And all the contents of the files in the path are erased.
Smilie
Is there any other way to work this out.

Thanks

ustrtok(3alleg4)						  Allegro manual						  ustrtok(3alleg4)

NAME
ustrtok - Retrieves tokens from a string. Allegro game programming library. SYNOPSIS
#include <allegro.h> char *ustrtok(char *s, const char *set); DESCRIPTION
This function retrieves tokens from `s' which are delimited by characters from `set'. To initiate the search, pass the string to be searched as `s'. For the remaining tokens, pass NULL instead. Warning: Since ustrtok alters the string it is parsing, you should always copy the string to a temporary buffer before parsing it. Also, this function is not re-entrant (ie. you cannot parse two strings at the same time). Example: char *word; char string[]="some-words with dashes"; char *temp = ustrdup(string); word = ustrtok(temp, " -"); while (word) { allegro_message("Found `%s' ", word); word = ustrtok(NULL, " -"); } free(temp); RETURN VALUE
Returns a pointer to the token, or NULL if no more are found. SEE ALSO
