2 Unix / Linux uudecode Command Examples

uudecode command is used to decode the ASCII representation that was created by the uuencode command. Please note that uuencode command encodes a binary file to ASCII text.

1. Basic uudecode Example

In this example, I have a file called “test.out”, which is a uuencoded file, as shown below.

# cat test.out
begin 644 /dev/stdout

2. Store the uudecode Output to a File

In this example, I know that the test.out is a uuencoded file of a compressed tar file. So, I’ll decode this file and store the output to a test.tar.gz file as shown below.

# uudecode -o test.tar.gz test.out

Now, verify to make sure this is showing the appropriate content after the decode.

# ls -l test.tar.gz
-rw-r--r--. 1 root root 131 Apr 10 23:12 test.tar.gz

# tar tvfz test.tar.gz
-rw-r--r-- root/root        10 2013-04-10 23:24 badblocks.txt
