How to join one file with multiple files in a directory in UNIX?

Dear folks
Hello

I have a one file called (file1) which the structure looks like this
Code:
1       gi|358484521|ref|NW_003764373.1|
1       gi|358484520|ref|NW_003764374.1|
1       gi|358484519|ref|NW_003764375.1|
.
.
.
30   gi|368484519|ref|NW_00449375.1|

In addition, I have around 300 files which can called (file2) in a directory with this structure:
Code:
gi|358484513|ref|NW_003764381.1| 1751 T C 0 1 1
gi|358484498|ref|NW_003764396.1| 481 A C 1 1 2
gi|358484498|ref|NW_003764396.1| 2603 T G 0 1 1

Now my desire output is join the Second column of file1 with first column of file2.

Code:
1  gi|358484513|ref|NW_003764381.1| gi|358484513|ref|NW_003764381.1| 1751 T C 0 1 1
1  gi|358484498|ref|NW_003764396.1| gi|358484498|ref|NW_003764396.1| 481 A G 1 1 2
1  gi|358484498|ref|NW_003764396.1|  gi|358484498|ref|NW_003764396.1| 2603 A G 0 1 1

I was trying a for loop to get the join files for all of the 300 files in the directory but it does not happened.

I will appreciate if any one give me a suggestion.

NAME
git-symbolic-ref - Read, modify and delete symbolic refs SYNOPSIS
git symbolic-ref [-m <reason>] <name> <ref> git symbolic-ref [-q] [--short] <name> git symbolic-ref --delete [-q] <name> DESCRIPTION
Given one argument, reads which branch head the given symbolic ref refers to and outputs its path, relative to the .git/ directory. Typically you would give HEAD as the <name> argument to see which branch your working tree is on. Given two arguments, creates or updates a symbolic ref <name> to point at the given branch <ref>. Given --delete and an additional argument, deletes the given symbolic ref. A symbolic ref is a regular file that stores a string that begins with ref: refs/. For example, your .git/HEAD is a regular file whose contents is ref: refs/heads/master. OPTIONS
-d, --delete Delete the symbolic ref <name>. -q, --quiet Do not issue an error message if the <name> is not a symbolic ref but a detached HEAD; instead exit with non-zero status silently. --short When showing the value of <name> as a symbolic ref, try to shorten the value, e.g. from refs/heads/master to master. -m Update the reflog for <name> with <reason>. This is valid only when creating or updating a symbolic ref. NOTES
In the past, .git/HEAD was a symbolic link pointing at refs/heads/master. When we wanted to switch to another branch, we did ln -sf refs/heads/newbranch .git/HEAD, and when we wanted to find out which branch we are on, we did readlink .git/HEAD. But symbolic links are not entirely portable, so they are now deprecated and symbolic refs (as described above) are used by default. git symbolic-ref will exit with status 0 if the contents of the symbolic ref were printed correctly, with status 1 if the requested name is not a symbolic ref, or 128 if another error occurs.
