Parsing file to retrieve specific pattern

[Shishir]

I have a txt file with several rows. Each row contains several words separated by space. I want to print the values which have pattern like amenXXXXXXX (where length of X string is different in many rows). I tried grep with -o option and some other one-liners but not able to print only the words that have the pattern like amen. Indeed I want the output like:

amen2wit
amen3grps
amen0qw
amen8dbskm.....

I will appreciate your expert suggestions.

Are all amenXXXXXXX in the same column? If yes, you could just:

cut -f N

Where N is the column number.

What about this:

echo "no pattern
amen
amenXXX
foo amenBLA foo2
etc" > mytext.txt

grep -o 'amen[^ ]*' mytext.txt
amen
amenXXX
amenBLA

How do you want to deal with the pattern occurring more than once per row, if that happens?
