Sed and awk backslash characters
Hi,

I have a variable read from user input:
PROFILESROOTDIR="\\194.185.82.188\CMSRepository\EncodingProfiles"


awk -F"=" -v gr=$PROFILESROOTDIR '/ProfilesRootDirectoryFromXOEMachine/{$2=gr;}1' OFS="=" $CFGFILE > "${CFGFILE}_new"

For this awk to work properly I need to replace in the variable each \ character with \\\ using sed but I just can't manage to do that.

Thanks,
Bianca

ir-keytable

IR-KEYTABLE(1)							   User Commands						    IR-KEYTABLE(1)

NAME

       ir-keytable - a swiss-knife tool to handle Remote Controllers.

SYNOPSIS

       ir-keytable [OPTION]... --device [/dev/input/event* device]
       ir-keytable [OPTION]... --sysdev [ir class (f. ex. rc0)]
       ir-keytable [OPTION]... [for using the rc0 sysdev]

DESCRIPTION

       ir-keytable  is a tool that lists the Remote Controller devices, allows one to get/set IR keycode/scancode tables, test events generated by
       IR, and to adjust other Remote Controller options.

       Note: You need to have read permissions on /dev/input for most of the options to work.

OPTIONS

       -a, --auto-load=CFGFILE
	      Auto-load a table, based on a configuration file. Only works with sysdev.

       -c, --clear
	      clears the old table

       -d, --device=DEV
	      ir device to control

       -D, --delay=DELAY
	      Sets the delay before repeating a keystroke

       -k, --set-key=SCANKEY
	      Change scan/key pairs

       -p, --protocol=PROTOCOL
	      Protocol to enable (the other ones will be disabled). To enable more than one, use the option more than one time

       -P, --period=PERIOD
	      Sets the period to repeat a keystroke

       -r, --read
	      reads the current scancode/keycode table

       -s, --sysdev=SYSDEV
	      ir class device to control

       -t, --test
	      test if IR is generating events

       -v, --verbose
	      enables debug messages

       -w, --write=TABLE

       --usage
	      Give a short usage message

       -V, --version
	      print the v4l2-utils version

       Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options. Options can be combined
       together.

   The options arguments are:
       DEV    the /dev/input/event* device to control

       SYSDEV the ir class as found at /sys/class/rc

       TABLE  a file wit a set of scancode=keycode value pairs

       SCANKEY
	      a set of scancode1=keycode1,scancode2=keycode2.. value pairs

       PROTOCOL
	      protocol name (nec, rc-5, rc-6, other) to be enabled

       DELAY  Delay before repeating a keystroke

       PERIOD Period to repeat a keystroke

       CFGFILE
	      configuration file that associates a driver/table name with a keymap file

EXIT STATUS

       On success, it returns 0. Otherwise, it will return the error code.

EXAMPLES

       To list all connected Remote Controller devices:
	    ir-keytable

       To clean the keycode table and use a newer one:
	    ir-keytable -c -w /etc/rc_keymaps/nec_terratec_cinergy_xs

       To append more codes to the existing table:
	    ir-keytable -w /etc/rc_keymaps/nec_terratec_cinergy_xs

       To read the current keytable, on the second remote controller:	   ir-keytable -s rc1 -r
