lsfrom lists the files and/or dirs in a directory starting from
the given filename or the next one after that,
using the current locale collation order.
Consider a directory with a few files:
$ ls
A b B C(lsfrom is typically more useful in larger directories,
but to keep things simple let's use a small example here.)
Let's list the files after b:
$ lsfrom --after b/
B
CEquivalently the files from B:
$ echo $(lsfrom --from B)
B CWe can also list until:
$ lsfrom --until B
A
b
BNote the file (collation) order will depend on the locale in general:
$ LC_COLLATE=C echo $(lsfrom -f B)
B C b--from/--after can be combined with --until/--before.
Without any of these options, the output should be similar to ls -A,
but only 1 file per line.
The file of the path given does not need to exist (unless using --strict mode):
$ lsfrom -a /t
/tmp
/usr
/varIt is also possible to filter the listing with --dirs or --files.
A common use-case is continuing a program or script on the entries of a directory after a failure, etc:
$ myscript.sh $(lsfrom -f next)or only running a command on a subrange of files or dirs in a directory.
$ lsfrom --version
2.0
$ lsfrom -h
List directories files starting from file
Usage: lsfrom [--version] [-s|--strict] [-A|--all] [--dirs | --files]
[(-f|--from STARTFILE) | (-a|--after STARTFILE)]
[(-u|--until LASTFILE) | (-b|--before LASTFILE)]
lsfrom lists the files in a directory that follow from the given file
Available options:
-h,--help Show this help text
--version Show version
-s,--strict fail if specified file(s) do not exist
-A,--all include hidden (dot) files
--dirs Only list directories
--files Only list files
-f,--from STARTFILE files from STARTFILE
-a,--after STARTFILE files after STARTFILE
-u,--until LASTFILE files until LASTFILE
-b,--before LASTFILE files before LASTFILE
Tested on Linux (may also work on MacOS):
specifically it uses libc collation (wcscoll()) for file ordering.
It also uses ls to list files sorted in the locale collation
with the -A option to exclude ./ and ../ (ie coreutils).
