I stored results like this
VAR=`wc -l < ls.txt`
But the value of the wc gave me a padded number.
How do I strip the padding from $VAR?
Do you think I could use SED?
Except instead of a file input, have a variable redirection input? (2 Replies)

Example:

pvremove
pvremove(1M)pvremove(1M)NAME
pvremove - remove LVM data structure from a physical volume
SYNOPSIS DESCRIPTION
The command clears the LVM data structure on a disk, so that it is no longer an LVM physical volume. The device may then be used by the
file system or by other volume managers.
The operation is denied if pv_path is assigned to a volume group. The command only clears the LVM data structure on a disk if the disk
does not belong to a volume group. This avoids accidentally removing a valid physical volume under a volume group. If the physical volume
to be removed belongs to a volume group, use the command to first remove the volume group associated with the physical volume.
Arguments
recognizes the following arguments:
pv_path The character (raw) device path name of a physical volume.
EXTERNAL INFLUENCES
Environment Variables
determines the language in which messages are displayed.
If is not specified or is null, it defaults to "C" (see lang(5)).
If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).
EXAMPLES
Remove LVM data structure on the physical volume
