How to filter files when using scp to copy recursively?

Question

I need to copy all the .class files from the server to the local one with all the reserved files. e.g. server:/usr/some/unknown/number/of/sub/folders/me.class will be /usr/project/backup/some/unknown/number/of/sub/folders/me.class problem is that there is a lot of other useless files like .svn-base files that I don't want. how can i filter them so i only scp .class files?

Answer 1

I would recommend using something like rsync for this because of its include and exclude flags, for example: -

 rsync -rav -e ssh --include '*/' --include='*.class' --exclude='*' \ server:/usr/some/unknown/number/of/sub/folders/ \ /usr/project/backup/some/unknown/number/of/sub/folders/ 

Some other useful flags:

• -r for recursive
• -a for archive (basically all files)
• -v for verbose output
• -e to specify ssh instead of the default value (which should be ssh, in fact)

Answer 2

To exclude dotfiles in the base directory:

 scp -r [!.]* server:/path/to/something 

Answer 3

There are no filters in scp to filter files. For “advanced” things like this, I recommend using rsync:

 rsync -av --exclude '*.svn' user@server:/my/dir . 

(this line copies rsync from the remote folder to the current one)

Recent rsync tunnels over ssh are automatically the default.

Since you can scp , you must be in ssh order,
either script follow these steps or log in and execute ...

 # After reaching the server of interest cd /usr/some/unknown/number/of/sub/folders tar cfj pack.tar.bz2 $(find . -type f -name *.class) 

return back (exit) to the local server and scp ,

 # from the local machine cd /usr/project/backup/some/unknown/number/of/sub/folders scp you@server:/usr/some/unknown/number/of/sub/folders/pack.tar.bz2 . tar xfj pack.tar.bz2 

---

If you find that $(find ...) too long for your tar to change,

 find . -type f -name *.class | xargs tar cfj pack.tar.bz2 

---

Finally, since you keep it in /usr/project/backup/ ,
why do mining? Just save tar.bz2 , possibly with a date + timestamp.

With ssh based authentication enabled, the script will work.

 for x in `ssh user@remotehost 'find /usr/some -type f -name *.class'`; do y=$(echo $x|sed 's/.[^/]*$//'|sed "s/^\/usr//"); mkdir -p /usr/project/backup$y; scp $(echo 'user@remotehost:'$x) /usr/project/backup$y/; done

Below is the command for files.

scp `find. -maxdepth 1 -name "* .log" \! -name "hs_err_pid2801.log" -type f` root @IP: / tmp / test /

• IP will be the IP address of the destination server.
• -name "* .log" for included files.
• \! -name "hs_err_pid2801.log" for file exceptions.
• . current working directory.
• -type f for file type.

Below are the commands for the directory.

scp -r `find. -maxdepth 1 -name "lo *" \! -name "localhost" -type d` root @IP: / tmp / test /

You can customize the command above according to your requirement.

• Copy the source folder to somedir :

  cp -r srcdir somedir

• Delete all unnecessary files:

  find somedir -name '.svn' -exec rm -rf {} \ +

• run scp from somedir
