CrushClient Documentation
#

A leading "L" character instructs the client to apply the command to the local client versus to the remote client. lls would sit your current local folder, lcd changes the local folder. Only the file transfer commands do not have an "L" version. (put, get, diffput, diffget) If a path being referenced has a space in it, the path must be quoted. Example: put "some file.txt" "/some folder/my file.txt". Backslash quote escaping is permitted as well. The "local" client doesn't need to be local at all though, both clients can be remote and files can be streamed through the CrushClient. Commands can be sent into he background with a "&" at the end of them. Example:

put file.txt remote.txt&

---

There are different ways to start CrushClient. If started with a script, no input will be taken, all input will be read line by line from the script as if you were physically typing it. Don't forget the quit command at the end or the client will wait indefinitely for more input... A script is typically ended with two lines. wait, then quit.

java -jar CrushTunnel.jar
java -jar CrushTunnel.jar https://demo:demo@crushftp.com/demo/
java -jar CrushTunnel.jar https://demo:demo@crushftp.com/demo/ file://c:/temp/
java -jar CrushTunnel.jar script my_commands.txt
java -jar CrushTunnel.jar inline_script "connect https://demo:demo@crushftp.com/demo/;put file.txt;wait;quit;"

---

Example: http://user:pass@domain.com:port/path/ or https://crushftp.com/ or https://crushftp.com/demo/ The url must end with a slash. User and pass is optional in the URL, you will be prompted for them if omitted.

---

Commands#

connect url
lconnect url

---

Disconnects from the currently connected client, for use when you want to change what client your connected with.

disconnect
ldisconnect

---

Transfers file/directory from remote client to local client. Example: get test.txt or get test.txt test_local.txt or get /folder/test.txt file.txt or get /folder/test.txt /local/test.txt
reget will resume the download based on the target file's size.
There is no 'mget" command as the normal 'get' command supports one or many items, including pattern matching.

get /remote/file/path [local file path]
reget /remote/file/path [local file path]
get /remote/file/path/*.TXT [local file path]
get /remote/file/path/ABC???_*.TXT [local file path]

---

Transfers file/directory from local client to remote client. Example: put test.txt or put test.txt test_remote.txt or put /folder/test.txt file.txt or put /folder/test.txt /remote/test.txt
reput will resume the put based on the size of the remote item.
appe will start appending the current file to the target file.
move will copy, then delete the source.
There is no 'mput" command as the normal 'put' command supports one or many items, including pattern matching.

put /local/file/path [remote file path]
reput /local/file/path [remote file path]
appe /local/file/path [remote file path]
move /local/file/path [remote file path]
put /local/file/path/*.XML [remote file path]
put /local/file/path/*ABC*.TXT [remote file path]

---

Similar to the putdel command, but first calculates the differences between the directories and files and lists what actions it would do if you instead used putdel. It will list out the deletes and copy actions it would do to make the remote side match the local side. This command is available as of CrushClient 1.5.2 and above.

diffdir

---

Similar to the put command, but first calculates the differences between the files and then transfers just those differences. Remote side must be a CrushFTP server.

diffput

---

Similar to the get command, but first calculates the differences between the files and then transfers just those differences. Remote side must be a CrushFTP server.

diffget

---

Prints out a unix styled directory listing.

list
dir
ls
llist
ldir
lls

---

Deletes an item. Example: del /remote/test.txt

del /remote/path
ldel  /local/path

---

Gets info about the selected item and prints to the screen.

stat /remote/path
lstat /local/path

---

Lists the segments that are different between the two files.

diff local/path remote/path

---

Changes the current working directory for the local or remote client.

cd
cwd
lcd
lcwd

---

Prints the current working directory for the local or remote client.

pwd
lpwd

---

Creates a new folder.

mkd /remote/path
lmkd /local/path

---

Renames an item, both must be specified in the command for source and destination.

rename /remote/path1 /remote/path2
mv /remote/path1 /remote/path2
lrename /local/path1 /local/path2
lmv /local/path1 /local/path2

---

Toggles the use of FTP passive mode.

pasv
lpasv
----
The anything section is passed to the remote FTP server directly.
{{{
quote anything
lquote anything

---

Sets the modified date to the specified time.

mdtm /remote/path yyyyMMddHHmmss
lmdtm /local/path yyyyMMddHHmmss

---

Quits the CrushClient, aborting any in-progress transfers.

quit

---

Sets a configuration parameter on the client. Undocumented for now, use the UI in CrushFTP to setup a config on a connection item and then view the raw XML for the config param it configured.

config param value
lconfig param value

---

Sets a variable that can be later referenced, or sets different client properties on how the client acts. Example: set max_threads 10

set param value

Param list:
download_threads (default = 0 which is unlimited)
upload_threads (default = 0 which is unlimited)
skip_modified_and_size (default is true)
skip_modified (default is false, ignored if skip_modified_and_size is true)
skip_size (default is false, ignored if skip_modified is true or skip_modified_and_size is true)
keep_date (default is true)
multithreaded (default is true)

---

Queues up commands in a list so they can later on be executed. Built a list of file transfers to do in a queue, then run it with the execute command. Useful for scripting load to the server.

queue {id} add command
queue {id} reset
queue {id} run

---

Waits for active transfers to complete with the local or remote client and prints occasional statistics about in-progress transfers.

wait
lwait

---

Pauses CrushClient for the specific milliseconds to impose delays in command processing.

delay {milli seconds}

---

Forces a one way copy/replace sync operation. Anything on the destination not found on the source is deleted. Use extreme care when using this command as a single typo would mean it erases the target you specified!

putdel /local/file/path [remote file path]

---

List the supported ciphers for HTTPS/FTPS/FTPES connections by making a test connection outbound to https://www.crushftp.com/
Set the cipher to use for SSL/TLS connections.
List the last used cipher for the prior connection.
Trust all certificates, regardless if they are expired, revokes, matching, etc. Use only for debug/dev purposes, but not for real world usage!

Start a tunnel with a server so you can connect through it. After starting you can connect through the tunnels port. Typically its 55555.

tunnel https://www.crushftp.com/        (you will be prompted for credentials)
tunnel https://demo:demo@www.crushftp.com/      (credentials provided inline in the URL)
tunnel list   (list running and stopped tunnels)
tunnel stop {id}   (stop a tunnel id you got from the list command, ids start at 1 and count up for each tunnel you create.  Once stopped, a tunnel id can't be started.)
tunnel log  (prints out the recent tunnel log messages)

connect http://127.0.0.1:55555/        (now you can connect normally through the tunnel that was just started)

• 'PUTSYNC' IS EXPERIMENTAL AND FLAWED! WARNING!
  

Performs a two way sync operation. Uses the modified date on items to decide which side has the latest copy and copies in both directions. It also uses its last known run time for the sync to decide which side has the correct items and deletes items it believes were deleted from one side from the other side too! If the logic fails here, it deletes items on both sides you didn't intend for. Extreme caution should be used when considering using this command. We don't have access to any time and dates except modified times, so the logic is flawed. If you copied an item with an older date modified than the last sync time to one side, it would then get deleted as it appears as if its old...and its missing from the other side, so its not supposed to be there. Do not use this command unless you fully understand everything mentioned or you will loose data...

putsync /local/file/path [remote file path]

Example script to do PGP encryption client side before uploading to a remote server (we have to turn off MD5 checking as the MD5 will no longer match if uploading to a CrushFTP server):

set md5_check false
config pgpEncryptUpload true
config pgpPublicKeyUploadPath /mypgpkeys/customer1_key.pub
connect https://user:pass@someserver.domain.com/
lcd /var/documents/
cd /
put test_file.txt
wait
quit
