Something like this | Code: | | find . -type f -maxdepth 1 | xargs ls -lt |
? |

Yes we can
Use "-r" too, meaning "ls -ltr" |

OK thanks, but how can I combine find with ls ?
Like this? find . -type f -maxdepth 1 | xargs ls -ltr |

toralf,
can you help me with this one, please?
I would like to move the first 1000 files in a directory sorted by date.
find . -type f -maxdepth 1 | xargs ls -latrh | head -n 1000 -exec mv {} /test \;
head: invalid option -- e
Try `head --help' for more information.
find: warning: you have specified the -maxdepth option after a non-option argument -type, but options are not positional (-maxdepth affects tests specified before it as well as those specified after it). Please specify options before other arguments.
xargs: ls: terminated by signal 13
What's the problem? 
I mean, I would like to put the move command after find . -type f -maxdepth 1 | xargs ls -lt |

Hhm, you should really try to use "man head" "man find"  - but nevertheless here's a simple example : | Code: | | find . -type f -maxdepth 1 | xargs ls -latrh | head -n 1000 | awk ' { print $9 } ' | while read line; do echo mv $line /test; done |

Used the man, but with no luck.
find . -type f -maxdepth 1 | xargs ls -latrh | head -n 10 | awk ' { print $9 } ' | while read line; do echo mv $line /test; done
find: warning: you have specified the -maxdepth option after a non-option argument -type, but options are not positional (-maxdepth affects tests specified before it as well as those specified after it).
Please specify options before other arguments.
mv /test
mv /test
mv /test
mv /test
mv /test
mv /test
mv /test
mv /test
mv /test
mv /test
ls -l /test
total 0
This is just not working |

To avoidan error mesg from find command, prefer | Code: | | find . -maxdepth 1 -type f |
and replace (obviously) the "." by that directory where you expect the 1000 files |

Thanks. Did that, the point is that the destination folder : /test is blank |

1. You should read the man page of each command to understand what it does and understand what you're doing.
2. To list files that are going to be moved, use | Code: | | find /path/to/dir/ -maxdepth 1 -type f -print0 | xargs -0 ls -Qltr | head -n 1000 | less |
find selects all file entries in specified directory and passes the list to ls via xargs (find's -print0 and xargs's -0 are used in case you have file names with spaces). ls sorts the list on mtime and pipes it into head which selects the first 1000.
If you what you see matches the 1000 files you want to move,
3. Move'em with mv in one go: | Code: | | find /path/to/dir/ -maxdepth 1 -type f -print0 | xargs -0 ls -Q1tr | head -n 1000 | xargs mv -iv -t /path/to/dest/ |
Important: the first ls command uses -l (lower case L) to list all details, the second one uses -1 (digit one) to display the file name alone so there's no need to cut it out with awk or cut.
Replace /path/to/dir with the path to the directory that contains all the files and /path/to/dest with the directory you want to move the files to.
