Xargs
Hello, I need some help with xargs
Code:
$ ls
aaa  bbb  ccc  ddd

Code:
$ ls | xargs -I{} ls -la {}
-rw-rw-r--. 1 xxx xx 0 May 30 20:04 aaa
-rw-rw-r--. 1 xxx xx 0 May 30 20:04 bbb
-rw-rw-r--. 1 xxx xx 0 May 30 20:04 ccc
-rw-rw-r--. 1 xxx xx 0 May 30 20:04 ddd

it's possible to have output like this with xargs:
Code:
$ ls | xargs -I{} ls -la {}
-----> aaa
-rw-rw-r--. 1 xxx xx 0 May 30 20:04 aaa
-----> bbb
-rw-rw-r--. 1 xxx xx 0 May 30 20:04 bbb
-----> ccc
-rw-rw-r--. 1 xxx xx 0 May 30 20:04 ccc
-----> ddd
-rw-rw-r--. 1 xxx xx 0 May 30 20:04 ddd

Also for loop is another option:
Code:
name=$( basename $0 )

for file in *
do
        [ "$file" == "$name" ] && continue
        echo "-----> "$file"
        ls -la "$file"
done
