Line feeds ....

[dbeez]

Hi,

I have a simple text file that is stacked like this

item1
item2
item3

I want it to be stacked like this

item1,item2,item3

But when I use

sed -e 's/\/r/,/g'

or any variants thereof, I still see the original text in pico ???

What am I doing wrong ??

Thanks

Hi

Although your question belong to the UNIX Scripting forum, let's have the other possibilities here too.

awk 'BEGIN{ORS=","}1'
[gray]# or[/gray]
sed -n '1h;1!H;${g;y/\n/,/;p}'

Hi feherke,

I'm trying to learn something about sed from your example (I've only really used it for search-and-destroy in the past) but can't get it to work on Solaris 9:

[tt]$ ls | sed -n '1h;1!H;${g;y/\n/,/;p}'
sed: command garbled: 1h;1!H;${g;y/\n/,/;p}
$[/tt]

...or on Linux (sed 3.0.2 or 4.0.7):

[tt]$ ls | sed -n '1h;1!H;${g;y/\n/,/;p}'
sed: -e expression #1, char 18: strings for y command are different lengths
$[/tt]

What I'm usually more intersted in is adding line feeds, so I would be interested in your solution to that as well.

sed -n '1h;1!H;${[highlight];[/highlight]g;y/\n/,/;p[highlight];[/highlight]}'

Hope This Helps, PH.

Hi

I use GNU [tt]sed[/tt] version 4.1.2. You are right, with version 3.02.80 the [tt]y///[/tt] command seems to not work with metacharacters so use [tt]s///[/tt] :

sed -n '1h;1!H;${g;s/\n/,/g;p}'

Regarding the problem on Solaris, I think will remain an eternal mistery for me. Appearantly that [tt]sed[/tt] is unable to group commands with braces.

Thanks PHV, so the block brackets need to appear as separate sed commands?

That fixes it for Solaris sed, but not Linux:

[tt]$ ls | sed -n '1h;1!H;${;g;y/\n/,/;p;}'
sed: -e expression #1, char 19: strings for y command are different lengths
$[/tt]

However this did work for me (^J entered using Ctrl-V, Ctrl-J in vi-editing mode):

[tt]$ ls | sed -n '1h;1!H;${;g;y/\^J/,/;p;}'[/tt]

And so did this:

[tt]$ ls | sed -n '1h;1!H;${;g;y/\
/,/;p;}'[/tt]

And to answer my other question, this changed the output back again:

[tt]$ ls | sed -n '1h;1!H;${;g;y/\^J/,/;p;}' | sed 'y/,/\^J/'[/tt]

Thanks for the clarification Feherke.

Hi

Interesting solution, that [tt]^J[/tt]. But on my machine is rather strange. I get [tt]bash: $: command not found[/tt].
