hi forums
i need help with a little problem i am having.
i need to count the number of fields that are in a saved variable so i can use that number to make a different function work properly.
is there a way of doing this without using SED/AWK?
anything would be greatly appreciated (4 Replies)
I want to sort lines by how many times a string occurs in each line (the most times first).
I know how to do this in two passes (add a count field in the first pass then sort on it in the second pass).
However, can it be done more optimally with a single AWK command? My AWK has improved... (11 Replies)

I currently pepend and equals sign to the front of the words I want to leave out in the finished test, =perpendicular, for example. I am able to number the blanks using a variable in LaTeX. I would like to... (8 Replies)

Hi,
let's say an input looks like:
A|C|C|D
A|C|I|E
A|B|I|C
A|T|I|B
as the title of the thread explains, I am trying to get something like:
1|A=4
2|C=2|B=1|T=1
3|I=3|C=1
4|D=1|E=1|C=1|B=1
i.e. a count of every character in each field (first column of output) independently, sorted... (4 Replies)

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [ options ] 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.
-jn m Join on the mth field of file n. If n is missing, use the mth field in each file.
-o list
Each output line comprises the fields specifed 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.
