Could you please advise on the following: I have two space-delimited files with 9 and 10 columns, respectively, with exactly the same values in column 1. However, the order of column 1 differs between the two files, so I want to sort both files by column 1, so that I can align them and concatenate them into a 19 column file.
If I want to sort by column 1, I usually use "sort -k 1,1 -g". I have done this hundreds of times and I have never had a problem with it.
This is the first time ever that the sort function has given a different output for the two files, despite using identical commands:
and
Why is this happening despite identical commands? I'm especially puzzled because I have never encountered this before.
Hi--
Ok. I have now found that:
find -x -ls
will do what I need as far as finding all files on a particular volume. Now I need to sort the results by the file's modification date/time.
Is there a way to do that?
Also, I notice that for many files, whereas the man for find says ls is... (8 Replies)

Hi All
I have a flat text file. Each line in it contains a "/full path/filename". The last three columns are predictable, but directory depth of each line varies.
I want to sort on the last three columns, starting from the last, 2nd last and 3rd last. In that order. The last three columns... (6 Replies)

Hi,
I have a problem with a shell script.

comm
comm(1) User Commands comm(1)NAME
comm - select or reject lines common to two files
SYNOPSIS
comm [-123] file1 file2
DESCRIPTION
The comm utility reads file1 and file2, which must be ordered in the current collating sequence, and produces three text columns as output:
lines only in file1; lines only in file2; and lines in both files.
If the input files were ordered according to the collating sequence of the current locale, the lines written will be in the collating
sequence of the original lines. If not, the results are unspecified.
OPTIONS
The following options are supported:
-1 Suppresses the output column of lines unique to file1.
-2 Suppresses the output column of lines unique to file2.
-3 Suppresses the output column of lines duplicated in file1 and file2.
OPERANDS
The following operands are supported:
file1 A path name of the first file to be compared. If file1 is -, the standard input is used.
file2 A path name of the second file to be compared. If file2 is -, the standard input is used.
USAGE
See largefile(5) for the description of the behavior of comm when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
EXAMPLES
Example 1: Printing a list of utilities specified by files
If file1, file2, and file3 each contain a sorted list of utilities, the command
example% comm -23 file1 file2 | comm -23 - file3
prints a list of utilities in file1 not specified by either of the other files. The entry:
example% comm -12 file1 file2 | comm -12 - file3
prints a list of utilities specified by all three files. And the entry:
example% comm -12 file2 file3 | comm -23 -file1
prints a list of utilities specified by both file2 and file3, but not specified in file1.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of comm: LANG, LC_ALL, LC_COLLATE,
LC_CTYPE, LC_MESSAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 All input files were successfully output as specified.
>0 An error occurred.
