Error: no “print“ mailcap rules found for type “text/plain“解决

博文背景

作者一直想搞明白Linux下的print命令如何使用？

直接print hello.txt会报错

Error: no "print" mailcap rules found for type "text/plain"

具体操作

ubuntu@139:~/temp $ cat /etc/mailcap | egrep print
application/x-troff-man; /usr/bin/nroff -mandoc -Tutf8; copiousoutput; print=/usr/bin/nroff -mandoc -Tutf8 | print text/plain:-
text/troff; /usr/bin/nroff -mandoc -Tutf8; copiousoutput; print=/usr/bin/nroff -mandoc -Tutf8 | print text/plain:-
text/plain; view %s; edit=vim %s; compose=vim %s; test=test -x /usr/bin/vim; print=cat %s; needsterminal
application/x-tar; /bin/tar tvf '%s'; print=/bin/tar tvf - | print text/plain:-; copiousoutput
application/x-gtar; /bin/tar tvf '%s'; print=/bin/tar tvf - | print text/plain:-; copiousoutput
application/x-ustar; /bin/tar tvf '%s'; print=/bin/tar tvf - | print text/plain:-; copiousoutput
ubuntu@139:~/temp $ ls
hello  hi.txt
ubuntu@139:~/temp $ cat hi.txt 
hello
ubuntu@139:~/temp $ print hi.txt 
hello

这是我编辑mailcap文件后的情况，注意看这一行

text/plain; view %s; edit=vim %s; compose=vim %s; test=test -x /usr/bin/vim; print=cat %s; needsterminal

也就是在text/plain后面添加一个print命令的规则即可，就是这么简单。
