No. Sorting a file will not turn a single line in one file into seven lines in another file.
And, neither
cat nor
grep will split or combine lines. So..., the format of Junaid Subhani's two files (
/opt/jbin/server.log.tmp and
/opt/jbin/log/server.log.2015-05-02-18) is different; and
cat and
grep are not going to reformat those files to Junaid Subhani's unspecified desired file format.
