Try this, 剛好是 14 個連續數字，才會echo出東西

echo "./12M-20120419010203-aaaa-bbb-ccc.log" | sed -n "s/.*-\([0-9]\{13\}\)-.*/\1/p" 

echo "./12M-20120419010203-aaaa-bbb-ccc.log" | sed -n "s/.*-\([0-9]\{14\}\)-.*/\1/p" 

echo "./12M-20120419010203-aaaa-bbb-ccc.log" | sed -n "s/.*-\([0-9]\{15\}\)-.*/\1/p" 

所以你可以判斷stdout吐出來的字串是否有長度不為0來判斷是否match
如下:

# Ref: stdio buffering: http://www.pixelbeat.org/programming/stdio_buffering/
# Default Buffering modes:
#    stdin  -> is always buffered
#    stderr -> is always unbuffered
#    if stdout is a terminal then buffering is automatically set to line buffered, else it is set to buffered
