<3> Buon giorno.
<4> hello. I have a list of records each consisting of 10 fields. I want to sort them usinf the 10th field but when I do say awk '{print $10 " "$4}' $4 overwrites the 10th field. Can anyone help please
<5> mag_, why don't you "man sort"?
<4> surprisingly a {print $4 " " $10} looks just fine
<4> Rado: i am just wondering what i'm missing here using awk
<5> mag_, typo.
<4> Rado: where?
<5> "$ -> " $
<4> Rado: maybe it is the field separators? the last one ends with no space but a newline
<4> Rado: its not a typo. the only difference I can see is the last field ending with an \n instead of a space
<4> well i solved it doing a {print $10 "\t\t\t\t" $2} , but durely its not the proper way. thanks anyways
<4> surely*
<5> Uh, I don't understand.
<5> Maybe this helps clarifiy: http://www.catb.org/~esr/faqs/smart-questions.html
<5> What does your "solution" now do different that your original attempt?
<5> that->than
<4> when I print the field $10 before $x where x is anything, $x overwrites $10 in the output. Say I have "longish" in "foo" in $x, then i get a "foogish"
<4> "longish" in $10
<5> You're doing something wrong then, because here it works. See the "Examples" in "man nawk", the "reverse fields" example wouldn't be possible if that were true.
<4> Rado: i've been going through the gawk manual and couldnt find the proper solution. I tried modifying OFS any FIELDWIDTH's but nothing. that was all i could find
<5> this works here: echo 'bla fasel kkk'|nawk '{print $3 $2 $1}'
<4> Rado: i know. there is certainly something wrong with the format of my input
<4> Rado: it is a long text file
<5> If you have a format error of the source-file, then how does your "solution help"?
<4> Rado: i indent the second field so that it does now overwrite
<4> does not*
<5> mag_, you have not understood: there is _NO_ overwriting at all.
<5> Whatever you do with the "print" cmd, it will _never_ change any data.
<4> Rado: it does not _change_ that is the output generated on my screen
<4> Rado: do you mind if i paste a couple of lines in your private? i don't want to flood here

<6> "mag_" at 85.107.117.239 pasted "Field $10 gets overwriten" (10 lines, 516B) at http://sial.org/pbot/18295
<5> tag, paul, do you have some kind of "homepage" for this channel, where we could put some of the links from the topic so it becomes shorter?
<5> mag_, just literally copy&pasting your input line and awk cmd-line works fine here. Try the same: copy&paste.

<4> this is one line
<4> the output is on the page
<5> I know, I don't mean here, in your shell.
<7> works for me on awk and gnu awk
<5> echo the above line | awk cmd as pasted on page.
<4> Rado: i see
<5> beebum, what is "awk" when not "gawk"?
<7> what comes with openbsd
<7> you have to load gawk separate
<8> next best thing man made - awk
<9> next? i guess we are supposed to ask "why next", or "next to what"?
