Sort anomalie

Hi Don

Thank you for your posting. I too, discovered the -f option this evening and then I read your response when I came to post my finding.

The data you see above had many many iterations to try to get it to work to my requirements. My original output was produced in the printf statement beginning printf( " \bHOST=%s... ..); (one space and one backspace before the H)

From what I understood, the sort command, if issued against x.raw, the file to be sorted, with the following comand line

Code:
   sort -k1 -t '|' -o x.sorted  x.raw

should keep the first line invariant, but it does not. It appears to require the -f to almost meet my needs.


The manual states that the -f was to fold upper to lower case together to lowercase.

I really was after the ascii collating sequence. Ergo With the -f option, Date1 and Date2 are in the wrong place, but the first line is maintained as was desired.

Is it possible that the sort is missing an option to "just sort a column", purely respecting the ascii contents of the field?

If the above answer is no, then if it was up to me, I would request a -e parameter (when used with -t ). It would be used to stop interpretation of leading blanks and non-alpha characters.

In closing, thanks for your help and for the others in the forum who responded.

NAME
sort - sort lines of text files SYNOPSIS
sort [OPTION]... [FILE]... DESCRIPTION
Write sorted concatenation of all FILE(s) to standard output. Mandatory arguments to long options are mandatory for short options too. Ordering options: -b, --ignore-leading-blanks ignore leading blanks -d, --dictionary-order consider only blanks and alphanumeric characters -f, --ignore-case fold lower case to upper case characters -g, --general-numeric-sort compare according to general numerical value -i, --ignore-nonprinting consider only printable characters -M, --month-sort compare (unknown) < `JAN' < ... < `DEC' -n, --numeric-sort compare according to string numerical value -r, --reverse reverse the result of comparisons Other options: -c, --check check whether input is sorted; do not sort -k, --key=POS1[,POS2] start a key at POS1, end it at POS2 (origin 1) -m, --merge merge already sorted files; do not sort -o, --output=FILE write result to FILE instead of standard output -s, --stable stabilize sort by disabling last-resort comparison -S, --buffer-size=SIZE use SIZE for main memory buffer -t, --field-separator=SEP use SEP instead of non-blank to blank transition -T, --temporary-directory=DIR use DIR for temporaries, not $TMPDIR or /tmp; multiple options specify multiple directories -u, --unique with -c, check for strict ordering; without -c, output only the first of an equal run -z, --zero-terminated end lines with 0 byte, not newline --help display this help and exit --version output version information and exit POS is F[.C][OPTS], where F is the field number and C the character position in the field. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key. SIZE may be followed by the following multiplicative suffixes: % 1% of memory, b 1, K 1024 (default), and so on for M, G, T, P, E, Z, Y. With no FILE, or when FILE is -, read standard input. *** WARNING *** The locale specified by the environment affects sort order. Set LC_ALL=C to get the traditional sort order that uses native byte values. AUTHOR
