My requirement is to list all files in a directory, except files ending with a ~ (backup files).
I tried to use command:
ls -l | grep -v ~
I get this output:
asdasad
asdasad~
file_names.txt
normaltest.txt
target_filename
testshell1.sh
testshell1.sh~
testshell2.sh
testshell2.sh~
testtwo.txt
testtwo.txt~
test.txt

I want to get only these files:
asdasad
file_names.txt
normaltest.txt
target_filename
testshell1.sh
testshell2.sh
testtwo.txt
test.txt
linux command-line filenames

ls -l | grep -v ~
The reason this doesn't work is that the tilde gets expanded to your home directory, so grep never sees a literal tilde. (See e.g. Bash's manual on Tilde Expansion.) You need to quote it to prevent the expansion, i.e.
ls -l | grep -v "~"
Of course, this will still remove any output lines with a tilde anywhere, even in the middle of a file name or elsewhere in the ls output (though it's probably not likely to appear in usernames, dates or such).
If you really only want to ignore files that end with a tilde, you can use
ls -l | grep -v "~$"

For one particular use case I've used shell filename expansion to do something similar. I've been using it since about 2003, which means it has worked on a very wide variety of shell implementations on different kinds of systems. (here I also use -C because I want a nice display in sorted columns)
ls -C *[!~]
(a limitation with using shell filename expansion is of course is that a directory with very large number of (non-backup) files will cause the expansion to exceed the available argument list size, though on most modern systems this limit is quite high, often 250KB or more, sometimes much more)
