Shell Programming and Scripting

Hi Gurus,

I am a starter with shell script. Help me to achieve this. I have a file with lines given below.

line1
line2
line3
.
.
etc

How can I arrange the file which should look like
line1,line2,line3,..,..,etc

Any help on this is appreciated.

Try this:

Code:

cat file | while read a
do
echo "$a,\c"
done

Code:

> cat file145
ColA ColB
1 2
2 x
3 y
4 c
5 q

> tr "\n" "," <file145 ; echo
ColA ColB,1 2,2 x,3 y,4 c,5 q,

Hi,

You can also do it like this:

Code:

tr "\n" "," < filename

/Lakris

It means "translate all newline to comma in the file filename"

Thanks for the support.
I am able to do with options given by Joeyg and Lakris. The option given by Bluescreen make every line to print with additional ", \c" at the end.

Also I require help on the output. Like if the content of a file is given below

ABC
ACB
ADB
BCD
BDC
BEF

How to arrange the file in below given pattern?
ABC,ACB,ADB
BCD,BDC,BEF

Any help on this will be appreciated.

Hope this will do

awk '{ if(substr($0,1,1) != prev_char)
{ printf("\n%s",$0); prev_char=substr($0,1,1); }
else printf(",%s",$0);
}' filename

Another approach:

Code:

awk '{ORS=!(NR%3)?"\n":","}1' file
