Hi All

This is just a study note of 'inode'


$ ls -li
....
1926029 drwxrwxr-x 3 key9 key9 4096 2006-11-30 14:53 Gnu Utils
....

$ find . -inum 1926029 -print
../Gnu Utils
$ find . -inum 1926029 -print | xargs ls -l
ls: ./Gnu: No such file or directory
ls: Utils: No such file or directory


So 'find' send the dictionary name but it seems xargs treated it as
separated.
any ideas?
I don't means using -exec 'ls -l' {} \;

Hello,

two options:
modify the IFS (space by default), see man your_shell
or
use a while loop:

find . -inum 1926029 -print |while read LINE ;do ls -l $LINE ;done

hope this you.

thank you and this works, buy have to add '"':

$ find . -inum 1926029 -print |while read LINE ;do ls -l "$LINE" ;done

and what I want to know is can I using way like this to xargs?

maybe something like :

(it will NOT WORK!!)
$echo "'find . -inum 1926029 -print '" | xargs ls -l

the idea is 'find' send the resoult to some tools and the tools give out
resoult which xargs can understand

IFS has no impact on xargs and that variable shouldn't be in the
environment.

However, it has an impact on "read" and on variable expansions
when not quoted.

find . -inum 1926029 -print |
while IFS= read -r LINE; do
ls -ld -- "$LINE"
done

(which doesn't work for multiline file names).

In order to pipe find to xargs, you need to post-process the
output of find so that it is compatible with the input format
expected by xargs (by default, they are not compatible unless
you use the GNU/BSD specific -print0|xargs -r0)

One way to do it is:

find .//. -inum 1926029 -print |
sed 's/./\\&/g' | awk '
{
if (NR > 1) {
printf "%s", line
if ($0 !~ /\\\/\\\//) printf "\\"
print ""
}
line = $0
}
END { print line }'

Either
find . -inum 1926029 -print0 | xargs -0 ls -l
or
find . -inum 1926029 | xargs -i ls -l {}
