In bash shell scripting, I have users.txt file.
sort -t: -k 3n users.txt gives me
gg:g@g.g: ff:f@f.f:5 gdr:d@sd.ds:5 g:w@f.com:8 r:w@d.com:85 qaws:aaa@d.com:789 qaz:a@s.com:789 vcf:d@c.com:855 op:popo@ppoo.po:6465 zx:a@c.com:7845 az:a@aa.com:7894 w:a@a.com:7894 h:g@g.com:7899 lp:l@l.com:8888 t:s@s.com:85474 dssdfsdf:fssdf@mbhkj.sdf:654654 u:f@g.comn:6546546 a:a@a.com:7894561 tt:t@t.t:1234567890
This is ok. But I need 3rd column which contain only phone number in reverse order i.e. descending order. How to achieve that?
I need like
tt:t@t.t:1234567890 a:a@a.com:7894561 u:f@g.comn:6546546 dssdfsdf:fssdf@mbhkj.sdf:654654 t:s@s.com:85474 lp:l@l.com:8888 and so on...

You could add an r (short for “reverse”) to the order column specification:
$ sort -t: -k 3nr users.txt # Here ---------^
