如何更改文件的修改/创建日期？

#1 楼

touch filename

touch -d "2 hours ago" filename

touch -d "$(date -R -r filename) - 2 hours" filename

#2 楼

find -print | while read filename; do
    # do whatever you want with the file
    touch -t 201203101513 "$filename"
done

#3 楼

touch -a -m -t 201512180130.09 fileName.ext

-a = accessed
-m = modified
-t = timestamp - use [[CC]YY]MMDDhhmm[.ss] time format

`-r FILE' `--reference=FILE'
     Use the times of the reference FILE instead of the current time.
     If this option is combined with the `--date=TIME' (`-d TIME')
     option, the reference FILE's time is the origin for any relative
     TIMEs given, but is otherwise ignored.  For example, `-r foo -d
     '-5 seconds'' specifies a time stamp equal to five seconds before
     the corresponding time stamp for `foo'.  If FILE is a symbolic
     link, the reference timestamp is taken from the target of the
     symlink, unless `-h' was also in effect.

touch -r "file" -d '+8 hour' "file"

for i in *; do touch -r "$i" -d '+8 hour' "$i"; done

#!/bin/bash

# find specific files
files=$(find . -type f -name '*.JPG')

# use newline as file separator (handle spaces in filenames)
IFS=$'\n'

for f in ${files}
do
 # read file modification date using stat as seconds
 # adjust date backwards (1 month) using date and print in correct format 
 # change file time using touch
 touch -t $(date -v -1m -r $(stat -f %m  "${f}") +%Y%m%d%H%M.%S) "${f}"
done

根据图像中的元信息调整图像的日期将非常有用。可以使用ImageMagick的标识。例如'identify -verbose | grep -i date'，'identify -format％[exif：DateTime] '可能显示为'2015：01：08 10:19:10'（并非所有图像都有exif数据） 。这有效（使用sed将日期转换为touch可以处理的格式）：'touch -d $（identify -format％[exif：DateTime] $ f | sed -r's /：/-/; s /：/-/ ;'）$ f'
