Details:
These are actually two different questions, but I find them often found
together.
1)-I option is called 'replace-str', which to me is particularly confusing,
because by 'replace' I usually mean some sort of post-processing of my data.
The wording convenient to me (and I suspect, to many other people) would be
'substitute'.
Initially, I understood this option as if it replaces the input to xargs with
itself. That is, for the command:
AAA.txt:
line
BBB.txt:
line2
cat AAA.txt | xargs -I {} echo `cat BBB.txt'
I expected the final commannd to be
echo {}2
But the actual command is:
echo line2 line
2)There are no examples in the info xargs which could debunk my
misunderstanding.
