From string to int ?
hello guys i m new to shell scripting and can't find out why this structure is not right
I m guessing this happens because $LINESUM is a string . so how can i do this ?
i want my script to do so many loops as the number of the lines of one custom file.

Code:
#!/bin/bash

echo give me path name
read GIVENPATH
wc -l $GIVENPATH | cut -d" " -f1 $LINESUM
COUNTER=1
while [ $COUNTER -le $LINESUM ]; do
    echo $COUNTER
    ((COUNTER++))
done

types.db

TYPES.DB(5)							     collectd							       TYPES.DB(5)

NAME

       types.db - Data-set specifications for the system statistics collection daemon collectd

SYNOPSIS

	 bitrate    value:GAUGE:0:4294967295
	 counter    value:COUNTER:U:U
	 if_octets  rx:COUNTER:0:4294967295, tx:COUNTER:0:4294967295

DESCRIPTION

       The types.db file contains one line for each data-set specification. Each line consists of two fields delimited by spaces and/or horizontal
       tabs. The first field defines the name of the data-set, while the second field defines a list of data-source specifications, delimited by
       spaces and, optionally, a comma (",") right after each list-entry.

       The format of the data-source specification has been inspired by RRDtool's data-source specification. Each data-source is defined by a
       quadruple made up of the data-source name, type, minimal and maximal values, delimited by colons (":"): ds-name:ds-type:min:max. ds-type
       may be either ABSOLUTE, COUNTER, DERIVE, or GAUGE. min and max define the range of valid values for data stored for this data-source. If U
       is specified for either the min or max value, it will be set to unknown, meaning that no range checks will happen. See rrdcreate(1) for
       more details.

FILES

       The location of the types.db file is defined by the TypesDB configuration option (see collectd.conf(5)). It defaults to collectd's shared
       data directory, i. e. prefix/share/collectd/.

CUSTOM TYPES

       If you want to specify custom types, you should do so by specifying a custom file in addition to the default one (see FILES) above. You can
       do that by having multiple TypesDB statements in your configuration file or by specifying more than one file in one line.

       For example:

	TypesDB "/opt/collectd/share/collectd/types.db"
	TypesDB "/opt/collectd/etc/types.db.custom"

       Note: Make sure to make this file available on all systems if you're sending values over the network.
