How do I convert my output vendor_id : GenuineIntel to vendor_id = GenuineIntel using the cut command?
#!/bin/bash
VENDORID=`cat /proc/cpuinfo | grep 'vendor_id'|cut -d`=`-f 5`
vendor_id: GenuineIntel
echo $VENDORID

Avoid backquotes (used for sub-commands), do not use them as single quotes.Walter A– Walter A2016-06-01 22:03:10 +00:00Commented Jun 1, 2016 at 22:03

You can use translate:
vendorid=$(grep 'vender_id' /proc/cpuinfo | tr ':' '=')
printf "%s\n" "$vendorid"
I changed backticks to $(..) since they are easier to nest. Also remember to double quote your variable expansions $vendorid -> "$vendorid" or it will undergo word splitting.
tr will in this case change all colons to equal signs, eg:
% echo "a:b:c" | tr ':' '='
a=b=c

I also want to run a script for the utility from my CPU

@user3613649 Hopefully now you know how to progress? :-)
VENDORID=$(sed -n '/vendor_id/{s/:/=/p;q}' /proc/cpuinfo)

This is a good answer, care you elaborate what
{s/:/=/p;q} does - might not be obvious?Translate the character :into = with
tr ':' '=' < /proc/cpuinfo
Assign to a variable with
vendorid=$(tr ':' '=' < /proc/cpuinfo)
