/etc/profile error when logging in

When I log into one of my servers, I immediately get this error:

bash: /etc/profile: line 1835263: syntax error near unexpected token `newline'
bash: /etc/profile: line 1835263: `        UID=`/usr/bin/id -ru`'

What is this and how can I fix it? I've tried to look at the file in nano but as you can see it's on line 1,835,263, which seems very strange. The beginning is a ton of blank lines before getting to anything relevenat. Using grep I can see the actual contents of the file. What is going on? This is the contents of the file:

[root@host ~]# grep . /etc/profile
# /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

What you're showing me certainly doesn't have a line 1835263 but the issue appears to be in the custom entry here:


            ;;
        UID=`/usr/bin/id -ru`
    fi

I'm thinking it's missing double quotes " ". How long has this customization been in place?

It's not customized. i haven't messed with the profile file at all.

I'm not sure in that case but it is certainly modified:

[root@server ~]# grep . /etc/profile
# /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.
pathmunge () {
    case ":${PATH}:" in
        *:"$1":*)
            ;;
        *)
            if [ "$2" = "after" ] ; then
                PATH=$PATH:$1
            else
                PATH=$1:$PATH
            fi
    esac
}

cPanel adds it's customizations in the sections noted by comments - the issue in yours though is not in a cPanel specific area and I'm unsure what would have changed that.

Is there a way to reset it? I have a script i run on the servers but it only updates /etc/environment to get rid of warnings from Perl for locale issues.
