Read multiple text file in shell sccript
I need help. I need to read all current and incoming text file in the directory and change it's content to 0.

The following code change the content of the text file to 0, however, the code always assumes that the files are ALREADY present. Is there any way where I can change the file1_.txt, file_2.txt, file_3.txt with only .txt extension and still change the content of the .txt file
Code:
#!/bin/sh 

for file in file_1.txt file_2.txt file_3.txt
do
    awk '{ print "0" }' $file > tmp.tmp
    mv tmp.tmp $file
done

Thanks for the help!

git-annex-shell

git-annex-shell(1)					      General Commands Manual						git-annex-shell(1)

NAME

       git-annex-shell - Restricted login shell for git-annex only SSH access

SYNOPSIS

       git-annex-shell [-c] command [params ...]

DESCRIPTION

       git-annex-shell is a restricted shell, similar to git-shell, which can be used as a login shell for SSH accounts.

       Since  its  syntax  is  identical to git-shell's, it can be used as a drop-in replacement anywhere git-shell is used. For example it can be
       used as a user's restricted login shell.

COMMANDS

       Any command not listed below is passed through to git-shell.

       Note that the directory parameter should be an absolute path, otherwise it is assumed to be relative to the user's home directory. Also the
       first "/~/" or "/~user/" is expanded to the specified home directory.

       configlist directory
	      This outputs a subset of the git configuration, in the same form as git config --list

       inannex directory [key ...]
	      This checks if all specified keys are present in the annex, and exits zero if so.

       dropkey directory [key ...]
	      This drops the annexed data for the specified keys.

       recvkey directory key
	      This runs rsync in server mode to receive the content of a key, and stores the content in the annex.

       sendkey directory key
	      This runs rsync in server mode to transfer out the content of a key.

       commit directory
	      This commits any staged changes to the git-annex branch.	It also runs the annex-content hook.

OPTIONS

       Most options are the same as in git-annex. The ones specific to git-annex-shell are:

       --uuid=UUID
	      git-annex uses this to specify the UUID of the repository it was expecting git-annex-shell to access, as a sanity check.

HOOK

       After  content is received or dropped from the repository by git-annex-shell, it runs a hook, .git/hooks/annex-content (or hooks/annex-con-
       tent on a bare repository). The hook is not currently passed any information about what changed.

ENVIRONMENT

       GIT_ANNEX_SHELL_READONLY

	      If set, disallows any command that could modify the repository.

       GIT_ANNEX_SHELL_LIMITED
	      If set, disallows running git-shell to handle unknown commands.
