Tried both the options but did no help...
I tried /usr/bin/perl -i -pe 's/[^\u2103]//g' file.txt > newfile.txt -- It gave an empty newfile.txt and the content of file.txt got changed to the name of it.
sed -e 's/\°//g' -- did not replace the degree symbol either.
PS : The degree symbol is visible only when I select the Show/Hide button on MS Word other wise it doesn't appear. Files with this symbol are not getting processed.
Khedu.

COPY(3) 1 COPY(3)
copy - Copies file
SYNOPSIS
bool copy (string $source, string $dest, [resource $context])
DESCRIPTION
Makes a copy of the file $source to $dest.
If you wish to move a file, use the rename(3) function.
PARAMETERS
o $source
- Path to the source file.
o $dest
- The destination path. If $dest is a URL, the copy operation may fail if the wrapper does not support overwriting of existing
files.

If the destination file already exists, it will be overwritten.
o $context
- A valid context resource created with stream_context_create(3).
RETURN VALUES
Returns TRUE on success or FALSE on failure.

| | |
| 4.3.0 | |
| | |
