这几天又用到这个命令,Mark一下。
find ./someDir -name “*.php” -o -name “*.html” | tar -cf my_archive -T –
可以把目录下面的同一类型文件全部打包

这几天发现好多HEVC的视频居然在Win10 Explorer里面没有缩略图,一查才发现居然Win10没有自带HEVC解码器。
到微软商店一搜,HEVC Video Extensions,居然还要卖钱。微软真是…. 都不知怎么形容了。
网上搜了下,发现其实微软商店里面还有个HEVC Video Extensions from Device Manufacturer。这个是免费的,而且功能一模一样。
额… 还能说什么呢…
今天在研究Linux下增量备份的时候,发现了一个非常Genius的命令。
用这个命令即可以做到增量备份,又可以最少量的占用硬盘空间。
rm -rf backup.3
mv backup.2 backup.3
mv backup.1 backup.2
cp -al backup.0 backup.1
rsync -a --delete source_directory/ backup.0/
多的懒得写了,大家自己体会吧。:D

最近因转换视频格式需要,研究了一下目前的视频格式转换工具。
发现下面几个比较顺手的:
推荐两个Partition Magic的替代软件
可动态调整分区大小,分区,格式化什么的就更不在话下了。
PS:如果你用SSD的话,记得分区对齐。
Here are steps to setup a user and allow the user access only via FTP (i.e. no SSH) and also limit access to a specific (user home) directory on proftpd:
1. Add new user: adduser newusername
2. Set password: passwd newusername
3. Modify user home directory from default to a new folder:
usermod -d /target/directory username
4. Edit shells file: vi /etc/shells and add /dev/null at the end
5. Modify newusername entry in the passwd file: vi /etc/passwd to add /./ before the newusername so that the entry looks like this:
newusername:x:502:502::/home/ftp/./newusernamehomedirectory/:/dev/null
6. Edit /etc/proftpd/proftpd.conf file and uncomment the line DefaultRoot ~
grep -rnw '/path/to/somewhere/' -e 'pattern'
-r
or -R
is recursive,-n
is line number, and-w
stands for match the whole word.-l
(lower-case L) can be added to just give the file name of matching files.Along with these, --exclude
, --include
, --exclude-dir
flags could be used for efficient searching:
grep --include=\*.{c,h} -rnw '/path/to/somewhere/' -e "pattern"
grep --exclude=*.o -rnw '/path/to/somewhere/' -e "pattern"
--exclude-dir
parameter. For example, this will exclude the dirs dir1/, dir2/ and all of them matching *.dst/:
grep --exclude-dir={dir1,dir2,*.dst} -rnw '/path/to/somewhere/' -e "pattern"
This works very well for me, to achieve almost the same purpose like yours.
For more options check man grep
sudo apt-get clean
sudo apt autoremove –purge
sudo apt-get autoremove –purge
sudo purge-old-kernels
sudo apt autoremove
今天刚好有这个需求研究了一下,发现ffmpeg就可以实现。
$ ffmpeg -f gif -i infile.gif outfile.mp4
Mark一下
