Strange. Both of the solution work for me . Iam working on Linux red hat. What error you got for that
Code:
for loop

solution.

Ah that could be why I am on HPUX

can you try
Code:
sed -e

rather than
Code:
-i

.However it will not update the file directly. Can you try this.

Only GNU sed has -i option.
The previous code should have worked; the for loop scans the current directory.
"find" scans the current directory *tree* (recursively).
You can replace the for loop by a while loop with read, and connect with a pipe:

Code:
#!/bin/sh
find . -type f -name "*.py" -print |
while read fp
do
 cp -p "$fp" "$fp".old &&
 sed 's/Sept_2012/Oct_2012/g' "$fp".old > "$fp" &&
 rm -f "$fp".old
done

Note the safety enhancements:
Always quote "$variables" with unknown contents!
cp to a backup - mv breaks links!
An && at the end of a command only continues with the next command if successful.

Excellent the code works when I put it into a shell script only a couple of problems.

1) I didn't know how to get a log of the files changed unless I ran the command below
2) All the .py files it searched got touched so I get today's time stamp on the directories it looks in
Code:
#!/bin/sh
find . -type f -name "*.py" -print |
while read fp
do
 cp -p "$fp" "$fp".old &&
 sed 's/Sept_2012/Oct_2012/g' "$fp".old > "$fp" &&
 rm -f "$fp".old
done

Code:
find . -name "*.py"  -exec grep "Oct_2012" {} \;

Sorry I thought you want all files changed.
Replaced -print by -exec grep -l ...
that prints only the matching file names:

Code:
#!/bin/sh
search="Sept_2012"
replace="Oct_2012"
find . -type f -name "*.py" -exec grep -l "$search" {} \; |
while read fp
do
 echo "$fp"
 cp -p "$fp" "$fp".old &&
 sed "s/$search/$replace/g" "$fp".old > "$fp" && 
 rm -f "$fp".old
done

Hi MadeInGermany,

Yes you are right we should always use the quotes for the variable
Code:
" "

.I just forget that in my reply. Also thanks for giving some tips on using
Code:
mv

and
Code:
cp

.Smilie
