Transform hexadecimal information to binary using a Linux command

Question

I have this binary file on my Linux system...

 udit@udit-Dabba ~ $ cat file.enc

 Salted__s�bO��<0�F���Jw!���]�:`C�LKȆ�l

Using the hexdump command, I see its information like this:

 udit@udit-Dabba ~ $ hexdump -C file.enc

 00000000  53 61 6c 74 65 64 5f 5f  1b 73 a1 62 4f 15 be f6  |Salted__.s.bO...|

 00000010  3c 30 cc 46 ee 10 13 11  84 bf 4a 77 21 a4 84 99  |<0.F......Jw!...|

 00000020  0e 5d ef 11 18 3a 60 43  a0 4c 4b 1e c8 86 e6 6c  |.]...:`C.LK....l|

 00000030

Now I am given a file on some other system whose contents are like this:

 53 61 6c 74 65 64 5f 5f  1b 73 a1 62 4f 15 be f6

 3c 30 cc 46 ee 10 13 11  84 bf 4a 77 21 a4 84 99

 0e 5d ef 11 18 3a 60 43  a0 4c 4b 1e c8 86 e6 6c

And I need to find out that same exact binary information from this hexdump.

How can I proceed for that?

As @user786653 suggested, use the xxd(1) program:

xxd -r -p input.txt output.bin
