tput cols in RHEL 7 is incorrect while in RHEL 8 it works fine

[vp0585]

Hi,

While running simple_curse.sh in RHEL 7 & RHEL 8. I found a issue that "bsc_cols=$(tput cols)" variable is getting set as 80 in RHEL 7 while actual "$(tput cols) value is 183" see below example. In RHEL8 I didn't find this issue as "echo $(tput cols) is 182 & bsc_cols=182" as well

In RHEL 7.7

It seems that it's not a bug from our script but from RHEL.

I can reopen the issue if you provide me an example that I can test.
