I use AIX via telnet here at work, and I\'d like to know how to find files in a specific folder between a date range. For example: I want to find all files in folder X that were
I've tried to answer this question in a more complete way, and I ended up creating a complete script with options to help you understand the find
command.
The script oldfiles
is in this repository
To "create" a new find command you run it with the option -n
(dry-run), and it will print to you the correct find
command you need to use.
Of course, if you omit the -n
it will just run, no need to retype the find
command.
$ oldfiles [-v...] ([-h|-V|-n] | {[(-a|-u) | (-m|-t) | -c] (-i | -d | -o| -y | -g) N (-\> | -\< | -\=) [-p "pat"]})
-h, --help : Show this help.
-V, --version : Show version.
-v, --verbose : Turn verbose mode on (cumulative).
-n, --dry-run : Do not run, just explain how to create a "find" command
-a or -u : access (use) time
-m or -t : modification time (default)
-c : inode status change
-i N : minutes (default, with N equal 1 min)
-d N : days
-o N : months
-y N : years
-g N : N is a DATE (example: "2017-07-06 22:17:15")
-p "pat" : optional pattern to match (example: -p "*.c" to find c files) (default -p "*")
-\> : file is newer than given range, ie, time modified after it.
-\< : file is older than given range, ie, time is from before it. (default)
-\= : file that is exactly N (min, day, month, year) old.
$ oldfiles -a -i 10 -p"*.c" -\> -nvvv
Starting oldfiles script, by beco, version 20170706.202054...
$ oldfiles -vvv -a -i 10 -p "*.c" -\> -n
Looking for "*.c" files with (a)ccess time newer than 10 minute(s)
find . -name "*.c" -type f -amin -10 -exec ls -ltu --time-style=long-iso {} +
Dry-run
$ oldfiles -m -o 1 -p"*.h" -\< -nvv
Starting oldfiles script, by beco, version 20170706.202054...
$ oldfiles -vv -m -o 1 -p "*.h" -\< -n
find . -name "*.h" -type f -mtime +30 -exec ls -lt --time-style=long-iso {} +
Dry-run
$ oldfiles -mng "2016-12-01" -\=
find . -name "*" -type f -newermt "2016-11-30 23:59:59" ! -newermt "2016-12-01 23:59:59" -exec ls -lt --time-style=long-iso {} +
Of course, removing the -n
the program will run the find
command itself and save you the trouble.
I hope this helps everyone finally learn this {a,c,t}{time,min}
options.
You will also notice that the "ls" option ls OPT
changes to match the type of time you choose.
oldfiles
script:https://github.com/drbeco/oldfiles
If you use GNU find
, since version 4.3.3 you can do:
find -newerct "1 Aug 2013" ! -newerct "1 Sep 2013" -ls
It will accept any date string accepted by GNU date -d
.
You can change the c
in -newerct
to any of a
, B
, c
, or m
for looking at atime/birth/ctime/mtime.
Another example - list files modified between 17:30 and 22:00 on Nov 6 2017:
find -newermt "2017-11-06 17:30:00" ! -newermt "2017-11-06 22:00:00" -ls
Full details from man find
:
-newerXY reference
Compares the timestamp of the current file with reference. The reference argument is normally the name of a file (and one of its timestamps is used
for the comparison) but it may also be a string describing an absolute time. X and Y are placeholders for other letters, and these letters select
which time belonging to how reference is used for the comparison.
a The access time of the file reference
B The birth time of the file reference
c The inode status change time of reference
m The modification time of the file reference
t reference is interpreted directly as a time
Some combinations are invalid; for example, it is invalid for X to be t. Some combinations are not implemented on all systems; for example B is not
supported on all systems. If an invalid or unsupported combination of XY is specified, a fatal error results. Time specifications are interpreted as
for the argument to the -d option of GNU date. If you try to use the birth time of a reference file, and the birth time cannot be determined, a fatal
error message results. If you specify a test which refers to the birth time of files being examined, this test will fail for any files where the
birth time is unknown.
