That looks like you've got carriage returns in your file. They send you to the beginning of the line.

You could probably rewrite your script much more efficiently if we knew the format of your data, but try this band-aid fix meanwhile:

Code:
data=`tr -d '\r' < /proc/dahdi/1`

lsdahdi is a somewhat glorified 'cat /proc/dahdi/*' . Unlike that command, it sorts the spans with the proper order. It also formats the output slightly differently. perl v5.14.2 2010-03-03 LSDAHDI(8)
