Or:
Code:
while read line; do echo "$line""/alpha.jpg"; done < file

or:
Code:
awk '{print $0 "/alpha.jpg"}' file

Many thanks for reply, both

while read line; do echo "$line""/alpha.jpg"; done < file and
awk '{print $0 "/alpha.jpg"}' file


working great, but just want to know, there are many empty lines in file, so script printing for empty lines as well like that

/alpha.jpg
/alpha.jpg
/alpha.jpg
/alpha.jpg
/alpha.jpg
/alpha.jpg
/alpha.jpg

so is there any fix to ignore empty lines.


Thanks

Or,

Code:
perl -lne 'print /./ ? "$_/alpha.jpg" : $_' your_file
 
perl -lne '$_.="/alpha.jpg" if /./; print' your_file

perl -plne '$_.="/alpha.jpg" if /./' your_file
