Sure.

[ricardo at centos5 ~]$ grep release /etc/issue
CentOS release 5.11 (Final)
[ricardo at centos5 ~]$ uniq --version | grep uniq
uniq (GNU coreutils) 5.97
[ricardo at centos5 ~]$ uniq --skip-fields=1 --all-repeated

No error message is generated and uniq is waiting for stdin.

[ricardo at centos5 ~]$ uniq --help
Usage: uniq [OPTION]... [INPUT [OUTPUT]]
Discard all but one of successive identical lines from INPUT (or
standard input), writing to OUTPUT (or standard output).

Mandatory arguments to long options are mandatory for short options too.
  -c, --count           prefix lines by the number of occurrences
  -d, --repeated        only print duplicate lines
  -D, --all-repeated[=delimit-method] print all duplicate lines
                        delimit-method={none(default),prepend,separate}
                        Delimiting is done with blank lines.
  -f, --skip-fields=N   avoid comparing the first N fields
  -i, --ignore-case     ignore differences in case when comparing
  -s, --skip-chars=N    avoid comparing the first N characters
  -u, --unique          only print unique lines
  -w, --check-chars=N   compare no more than N characters in lines
      --help     display this help and exit
      --version  output version information and exit

A field is a run of whitespace, then non-whitespace characters.
Fields are skipped before chars.
