exec와 xargs 차이

exec와 xargs 차이

 

find . -name H* -exec ls -l {} \; executes the command ls -l on each individual file.

find . -name H* | xargs ls -l constructs an argument list from the output of the find commend and passes it to ls.

consider if the ouput of the find command produced:
H1
H2
H3

the first command would execute
ls -l H1
ls -l H2
ls -l H3

but the second would execute
ls -l H1 H2 H3
