Warning while sorting : A newline character was added to the end of file
Hi,
I am trying to sort a csv file which has say 10 lines each line having a row size that is upto 30183 no. of COLUMNS (Row length = 30183). There is a LINE FEED (LF) at the end of each line. When I try to sort this file say, based on the second FIELD using the below command,
there is a warning that appears in the command line
"Warning : A newline character was added to the end of file file1.dat"
Also, there are 10 empty lines that get added to the file file1.dat along with the sorted 10 lines data.
If for a particular line I reduce the row size to say a few 100 COLUMNS (Row size= say, 250) then this warning doesn't appear and no empty line gets added for that particular line.
I am running the script on ksh under AIX server.
Can anyone tell me why this is happening? Is this really because of the huge row length?

Hi All,
Is there any way to append a newline character at the end of a file(coma-separated file), through shell script?
I need to check whether newline character exists at the end of a file, if it does not then append it.

echo -ne HELLO > file.txt
and then, 'HELLO' is written into file.txt without the newline character to be added in the end of the file.
How is this possible to be done using sh instead of bash?
If I try something similar is SH, then inside... (3 Replies)

Hello all,
I have maybe a simple Problem - but I do not know to handle it.
All what I want, is to write a line to file without a newline at the end. It works with "echo -n" for all lines, but not for the last one. At the end of the file is always a "0a" (hex)
My small script:

combine
COMBINE(1)COMBINE(1)NAME
combine - combine sets of lines from two files using boolean operations
SYNOPSIS
combine file1 and file2
combine file1 not file2
combine file1 or file2
combine file1 xor file2
_ file1 and file2 _
_ file1 not file2 _
_ file1 or file2 _
_ file1 xor file2 _
DESCRIPTION
combine combines the lines in two files. Depending on the boolean operation specified, the contents will be combined in different ways:
and Outputs lines that are in file1 if they are also present in file2.
not Outputs lines that are in file1 but not in file2.
or Outputs lines that are in file1 or file2.
xor Outputs lines that are in either file1 or file2, but not in both files.
"-" can be specified for either file to read stdin for that file.
The input files need not be sorted, and the lines are output in the order they occur in file1 (followed by the order they occur in file2
for the two "or" operations). Bear in mind that this means that the operations are not commutative; "a and b" will not necessarily be the
same as "b and a". To obtain commutative behavior sort and uniq the result.
Note that this program can be installed as "_" to allow for the syntactic sugar shown in the latter half of the synopsis (similar to the
test/[ command). It is not currently installed as "_" by default, but you can alias it to that if you like.
