How to read and manipulate directories and files?

[LilTCLer]

I can't figure out how to read the contents of a directory that includes other directories and files.

For example, here is what I want to do.

1. cd to a particular directory.
2. read contents of the directories within, and manipulate the dir names so I can "grab" the 3 directories with the latest timestamps.
3. In each of the three dorectories above, I then will do a file exists for a particular file within.

My issue is trying to read and parse the contents of a particular directory.

Any ideas where to start?

Hi
[ul]
[li]get the list of directories with [tt]glob[/tt][/li]
[li]walk over the list with [tt]foreach[/tt] and for each[ul]
[li]get the modification time with [tt]file[/tt][/li]
[li]push the time-name pair in a second list with [tt]lappend[/tt][/li][/ul][/li]
[li]sort that second list with [tt]lsort[/tt][/li]
[li]walk over the first 3 elements of the sorted list with [tt]for[/tt] and for each[ul]
[li]extract the given element with [tt]lindex[/tt][/li]
[li]check if the searched file exist with [tt]file[/tt][/li][/ul][/li]
[/ul]

Thanks I'll give that a shot

mtime (modify time), is returned in decimal for example:

FP6_0_BZ020_20090915 - 1253047000
FP6_0_BZ021_20090916 - 1253107209
FP6_0_BZ022_20090917 - 1253182442
FP6_0_BZ023_20090918 - 1253272139
FP6_0_BZ024_20090919 - 1253368601
FP6_0_BZ025_20090920 - 1253438610
FP6_0_BZ026_20090921 - 1253542557
FP6_0_BZ027_20090922 - 1253641722

is there a way to convert this to date, time, etc?

Hi

mtime (modify time), is returned in decimal for example: [gray](...)[/gray] is there a way to convert this to date, time, etc?

Is there any reason to convert it ? For sorting numeric is the best and you need them only for sorting. Or am I wrong ?

To answer your question, [tt]clock[/tt] can be used to convert the Unix time into formatted string.

I may need to be able to search for a specific date and time later on in the script.

Hi

Got it. Then you indeed will need [tt]clock[/tt]. However I would think at converting the searched date & time into Unix time. Of course, which approach is better may depend on the task.
