There appear to be a number of errors in the manual page for eqn as follows: $ nroff -man ./eqn.1 > /dev/null ./eqn.1:20: a space character is not allowed in an escape name ./eqn.1:20: a space character is not allowed in an escape name ./eqn.1:35: a space character is not allowed in an escape name ./eqn.1:35: warning: numeric expression expected (got `j') ./eqn.1:37: a space character is not allowed in an escape name ./eqn.1:37: warning: numeric expression expected (got `i') ./eqn.1:45: a space character is not allowed in an escape name ./eqn.1:46: a space character is not allowed in an escape name ./eqn.1:47: a space character is not allowed in an escape name ./eqn.1:48: a space character is not allowed in an escape name ./eqn.1:49: a space character is not allowed in an escape name ./eqn.1:50: a space character is not allowed in an escape name ./eqn.1:51: a space character is not allowed in an escape name ./eqn.1:52: a space character is not allowed in an escape name ./eqn.1:186: a space character is not allowed in an escape name ./eqn.1:847: a space character is not allowed in an escape name Of these, I can confirm that the "j" error reported by groff above is definitely not a valid groff command: .nr a \n(. j This expands to .nr a 0j, and j is not a recognised groff unit.
Submitter: does this error still appears?
Has anything changed which would mean it doesn't appear any longer? Please tell me what to download to get the new version without the errors.
I ran nroff -man eqn.1 > /dev/null and I get no errors?
Thank you for your input Nathan. My version of nroff is as follows: $ /usr/bin/nroff --version GNU nroff (groff) version 1.19.2 The MD5 checksum of eqn.1 is as follows: $ md5 eqn.1 MD5 (eqn.1) = b9357013cc6e126c788b9fa281f06fa4 As far as I know there have been no changes in the ko-man port: https://svnweb.freebsd.org/ports/head/korean/man-doc/ To confirm this, I've just downloaded ko-man using pkg, and I copied the eqn.1.gz from /usr/local/share/man/ko/man1/eqn.1.gz and checked its md5 checksum: $ md5 eqn.1 MD5 (eqn.1) = b9357013cc6e126c788b9fa281f06fa4 This appears to be exactly the same file. Running the above nroff on the file gives this output: $ /usr/bin/nroff -man eqn.1 > /dev/null eqn.1:20: a space character is not allowed in an escape name eqn.1:20: a space character is not allowed in an escape name eqn.1:35: a space character is not allowed in an escape name eqn.1:35: warning: numeric expression expected (got `j') eqn.1:37: a space character is not allowed in an escape name eqn.1:37: warning: numeric expression expected (got `i') eqn.1:45: a space character is not allowed in an escape name eqn.1:46: a space character is not allowed in an escape name eqn.1:47: a space character is not allowed in an escape name eqn.1:48: a space character is not allowed in an escape name eqn.1:49: a space character is not allowed in an escape name eqn.1:50: a space character is not allowed in an escape name eqn.1:51: a space character is not allowed in an escape name eqn.1:52: a space character is not allowed in an escape name eqn.1:186: a space character is not allowed in an escape name grotty:<standard input>:10935: character above first line discarded eqn.1:847: a space character is not allowed in an escape name I also seem to have another nroff in /usr/local/bin/nroff. I tried with that: $ /usr/local/bin/nroff --version GNU nroff (groff) version 1.18.1 $ /usr/local/bin/nroff -man eqn.1 > /dev/null eqn.1:20: a space character is not allowed in an escape name eqn.1:20: a space character is not allowed in an escape name eqn.1:35: a space character is not allowed in an escape name eqn.1:35: warning: numeric expression expected (got `j') eqn.1:37: a space character is not allowed in an escape name eqn.1:37: warning: numeric expression expected (got `i') eqn.1:45: a space character is not allowed in an escape name eqn.1:46: a space character is not allowed in an escape name eqn.1:47: a space character is not allowed in an escape name eqn.1:48: a space character is not allowed in an escape name eqn.1:49: a space character is not allowed in an escape name eqn.1:50: a space character is not allowed in an escape name eqn.1:51: a space character is not allowed in an escape name eqn.1:52: a space character is not allowed in an escape name eqn.1:163: name expected (got a magic token): treated as missing eqn.1:186: a space character is not allowed in an escape name eqn.1:847: a space character is not allowed in an escape name The results seem nearly the same. Can you confirm the version of nroff you are using and the md5 checksum of the file eqn.1 are the same as mine?
