No. The sort utility sorts lines; not groups of lines. You can however, join pairs of lines, sort the result, and then split the sorted output into pairs of lines again. Assuming that there aren't any tab characters in your input file, a simple way to do it would be:
which with the following infile contents (modified so we can be sure that the correct even numbered lines in the output follow the same lines they followed in the input file):
produces the output:
Of course, if all of the even numbered lines in your input files are identical (as in your sample); you could delete the even numbered lines, sort the remaining lines, and reinsert the deleted lines.

This seems to be a question whose answer uses sed or awk.
For a file like:
a
b
c
d
e
How to swap the order of the line pairs, to end up with:
b
a
d
c
e
All lines from the original file need to wind up in the output file. (8 Replies)
I have a number of files in a directory named like this:
fooP1, fooN1, fooP2, fooN2 ... fooP(i), fooN(i).
I'd like to know how to combine each P and N pair into a single file, foo(i)
TIA

Hi,
I am trying to paste together two files which are like this-

Hi all,
Please guide. It has to do with parsing the input file names.
I have a fairly large number of files, I want to do some operations on them in a pairwise fashion (every file has a pair).
The names are in the following pattern, with the pairs of files named with _1 and _2 , the... (4 Replies)
Hi,
I would like to batch concatenate files by pairs. I have quite a few of them so I would not like to do that pair by pair separately.
the names of the file is of the type:
file1.fastq
newfile1_new.fastq
file2.fastq
newfile2_new.fastq
and so on...
I would like to concatenate file1... (2 Replies)

uniq
UNIQ(1) General Commands Manual UNIQ(1)NAME
uniq - report repeated lines in a file
SYNOPSIS
uniq [ -udc [ +n ] [ -n ] ] [ input [ output ] ]
DESCRIPTION
Uniq reads the input file comparing adjacent lines. In the normal case, the second and succeeding copies of repeated lines are removed;
the remainder is written on the output file. Note that repeated lines must be adjacent in order to be found; see sort(1). If the -u flag
is used, just the lines that are not repeated in the original file are output. The -d option specifies that one copy of just the repeated
lines is to be written. The normal mode output is the union of the -u and -d mode outputs.
The -c option supersedes -u and -d and generates an output report in default style but with each line preceded by a count of the number of
times it occurred.
The n arguments specify skipping an initial portion of each line in the comparison:
-n The first n fields together with any blanks before each are ignored. A field is defined as a string of non-space, non-tab charac-
ters separated by tabs and spaces from its neighbors.
+n The first n characters are ignored. Fields are skipped before characters.
