Shell Programming and Scripting

Thanks all, here's what i am trying to do, I am close but not there yet
I want to print the last line of script where the file doesn't terminate with a newline.
But checking if the last line is empty or not, i want to get the list, but it doesn't work exactly that way

Consider the following files, '$' in bold black is the command prompt, '$' in bold blue is the formatting character from -e flag

Code:

$ cat c.sh
apple$ cat b.sh
apple
$ cat a.sh
apple.sh

$ cat -e c.sh
apple$ cat -e b.sh
apple$
$ cat -e a.sh
apple.sh$
$
$ 

Both files b.sh and c.sh seem to have the last line as 'apple', but in c.sh the end of file is on the same line as 'apple' and in b.sh it's in the next line

I want to print filename and last line for only files of type c.sh and not b.sh

Code:

$ find . -type f -name "*.sh" -exec awk '{s=$0};END{if(s)print FILENAME,s}' {} \;
./b.sh apple
./c.sh apple
$ 

The above awk command doesn't differentiate between b.sh and c.sh

Thanks,

Elaborating on Subbeh's, how about:

Code:

awk '$0{last=$0};END{print FILENAME,last}'

Hi Ripat,
the new command now shows one more incorrect result too. The result should only display for c.sh

I attached the 3 .sh files here

Code:

$ find . -type f -name "*.sh" -exec awk '{s=$0};END{if(s)print FILENAME,s}' {} \;
./b.sh apple
./c.sh apple
$ find . -type f -name "*.sh" -exec awk '$0{last=$0};END{print FILENAME,last}' {} \;
./a.sh apple.sh
./b.sh apple
./c.sh apple

Windows files with CRLF?

I ftpd files unix to windows. So files in unix were originally created in windows.
Either way, i want to detect files not ending with a newline

Code:

$ tail -1 c.sh | wc -l
0

Don't know if this will behave the same way on your OS, but on my ubuntu, if i tail -1 c.sh | wc -l i will get a 0 instead of 1 when there is no end of line.

So this may help to detect such file with no newline character.(A check that the file is not empty should be carried out as well)

hi ctsgnb, this c.sh has only one line without having a new line that's why "wc -l" returns zero. c.sh can have multiple lines without having newline at the end of the file, so checking for zero doesn't work

I want to print list of filenames along with their last line where the file doesn't end with a new line
Thanks
