Full Discussion: Copying latest file into a folder
Top Forums Shell Programming and Scripting Copying latest file into a folder Post 302299839 by TonyFullerMalv on Saturday 21st of March 2009 05:03:22 PM

$ ls -tr folderA | tail -1
Will give you the newest file.

So you could use:
Code:
LATEST=`ls -tr folderA | tail -1`
cp "folderA/${LATEST}" "folderB/${LATEST}".$$

Put the above in a script and call it from cron (if running once per minute is enough?) and $$ will be a different PID each time the script runs.

Or use a script something like, if the newest file in FolderA is going to change names each time:
Code:
PREVLATEST=""
while [ 1 ]; do
LATEST=`ls -tr folderA | tail -1`
if [ "${LATEST}" != "${PREVLATEST}" ]; then
  cp "folderA/${LATEST}" "folderB/${LATEST}"
  PREVLATEST="${LATEST}"
done

Call the script thus: nohup ./scriptname & and it would just keep running (you might want to put a sleep in their somewhere!

mfontset_lookup

mfontset_lookup(3m17n)						 The m17n Library					    mfontset_lookup(3m17n)

NAME

       mfontset_lookup - Lookup a fontset.

SYNOPSIS

       MPlist * mfontset_lookup (MFontset * fontset, MSymbol script, MSymbol language, MSymbol charset)

DESCRIPTION

       Lookup a fontset. The mfontset_lookup() function lookups fontset and returns a plist that describes the contents of fontset corresponding
       to the specified script, language, and charset.

       If script is Mt, keys of the returned plist are script name symbols for which some fonts are specified and values are NULL.

       If script is a script name symbol, the returned plist is decided by language.

       o If language is Mt, keys of the plist are language name symbols for which some fonts are specified and values are NULL. A key may be Mt
	 which means some fallback fonts are specified for the script.
       o If language is a language name symbol, the plist is a FONT-GROUP for the specified script and language.  FONT-GROUP is a plist whose keys
	 are FLT (FontLayoutTable) name symbols (Mt if no FLT is associated with the font) and values are pointers to MFont.
       o If language is Mnil, the plist is fallback FONT-GROUP for the script.
       If script is Mnil, the returned plist is decided as below.
       o If charset is Mt, keys of the returned plist are charset name symbols for which some fonts are specified and values are NULL.
       o If charset is a charset name symbol, the plist is a FONT-GROUP for the charset.
       o If charset is Mnil, the plist is a fallback FONT-GROUP.
RETURN VALUE

	   It returns a plist describing the contents of a fontset. The plist should be freed by m17n_object_unref().
