shell pipeline to get a suffiently safe filename from a disk volume LABEL as a mount point (directory name) to mount a hotplugged device.

blklabel

blkid -s TYPE|egrep vfat |
  cut -d \: -f 1|
  xargs /sbin/blkid -c value|
  xargs perl -MFile::Util="" \
      -e '$it=File::Util->new();' \
      -e 'print for map{/LABEL=([^=]+)(?=[[:space:]][[:upper:]]+[=])*/;' \
      -e '($1 ? do{($_=$it->escape_filename($1))=~s{[[:space:]]}{_}g and qq[/media/byLABELISH/$_\n]}' \
      -e ' : q[])} grep {LABEL} @ARGV'

I purchased a USB hard disk storage device which had been formatted with a fat32 filesystem labelled "SP PHD U3". (Silicon Power).

We get a mount point that is like: /media/byLABELISH/SP_PHD_U3
