change multi lined file into one line seperated by commas 2

[pneumatic]

all,

using unix aix -
i'm in a rush (aren't we all!) and need to change a file with several lines...
example:
ca1245
fc6789
rd7452
dp0329

into a one line file seperated by commas(using the example above) ie:
ca1245,fc6789,rd7452,dp0329

any suggestions would be welcome. not perl please.
thankyou in advance.

very quick and dirty you could use something like this....

cat filename | while read LINE
do
echo "$LINE,\c" >> newfile
done

Then just edit the file to remove the last comma in the line.

I like the paste command for this.

paste -d, -s filename

so if
ca1245
fc6789
rd7452
dp0329

are in a file named my_items, then
paste -d, -s my_items
will produce:
ca1245,fc6789,rd7452,dp0329

It also works with standard input from the command line.
cat my_items | paste -d, -s -
also produces:
ca1245,fc6789,rd7452,dp0329
