Appending a word to the last line
Hi,

I would like to append input given id at last line of file.
For ex: In the following sample.txt file i would like to append the input given user id (after id6,id7) but it is adding on the next line instead same line.

Sample.txt
read=id1,id2,id3
write=id4,id5,id6

Quote:
#!/usr/bin/ksh
echo "Enter id"
read id
echo ","{$id} >> sample.txt
Thanks

GNU sed:
Code:
#!/usr/bin/ksh
echo "Enter id"
read id
sed -i '$ s/$/,'"$id"'/' sample.txt

Without "-i" option you can redirect output to /tmp/tempfile.$$ and then mv this file to "sample.txt".

sed 's/$/,'"$ID"'/' filename
