Hi.
I have a tab separated file that has a couple nearly identical lines. When doing:
sort file | uniq > file.new
It passes through the nearly identical lines because, well, they still are unique.

I want to look only at field x for uniqueness and if the content in field x is the... (1 Reply)
Hello;
I have a file consists of 4 columns separated by tab. The problem is the third fields. Some of the them are very long but can be split by the vertical bar "|". Also some of them do not contain the string "UniProt", but I could ignore it at this moment, and sort the file afterwards. Here is... (5 Replies)
Hey,
I'm sure this is answered somewhere but my Googling has turned up nothing. I have a file with data in the following format:
<desription of event> at <time and date>The desription of the event is variable length and hence when the list is displayed it is hard to easily see the date (and... (8 Replies)

In the below I am trying to use awk to match all the $13 values in input, which is tab-delimited,
that are in $1 of gene which is just a single column of text.
However only the line with the greatest $9 value in input needs to be printed.
So in the example below all the MECP2 and LTBP1... (0 Replies)
In the awk below I am trying to print the entire line, along with the header row, if $2 is SNV or MNV or INDEL. If that condition is met or is true, and $3 is less than or equal to 0.05, then in $7 the sub pattern :GMAF= is found and the value after the = sign is checked. If that value is less than...

For some reason I am having difficulty performing what should be a fairly easy task. I would like to print lines of a file that have a unique value in the first field. For example, I have a large data-set with the following excerpt:

PS003,001... (4 Replies)

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [-an] [-e s] [-o list] [-tc] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard
input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-o list
Each output line comprises the fields specified in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO sort(1), comm(1), awk(1).
BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
