Thanx,

but what if I have some new lines at the end of the file, and I want to delete that new line character?

Or :
sed -e '$s/.$//' file_in > file_out
The number of fullstops(periods) denote the number of characters to be deleted.

To remove 'empty' lines :
sed '/^$/d' filename > newfilename
To remove line(s) with just a space :
sed '/^ /d' filename > newfilename

To remove all newlines from a file,

awk '{printf $0}' file1 > file2

I am not sure if you meant to delete the last character of every line or the last character of the file. This should delete newline characters from the end of each line:
02:35:17 | cat dog
filename=$1
awk '{printf("%s ",$0)};END{print}' $filename
02:35:24 | cat testfile
alpha
beta
gamma
delta
02:35:35 | dog testfile
alpha beta gamma delta
02:35:43 |

I came across this method of concatenating strings while
studing for a test. It accomplishes the same thing as some
of the previous posts.

20:08:07 | cat testfile
alpha
beta
gamma
delta

20:08:17 | nawk '{list=list" "$1}END{print list}' testfile
alpha beta gamma delta

Here's some perl blasphemy to remove that last character or newline.

perl -pe 'chop if eof'
