▶ Softenv FAQ?
The information here is applicable to LSU HPC and LONI systems.
A user may choose between using /bin/bash and /bin/tcsh. Details about each shell follows.
System resource file: /etc/profile
When one access the shell, the following user files are read in if they exist (in order):
- ~/.bash_profile (anything sent to STDOUT or STDERR will cause things like rsync to break)
- ~/.bashrc (interactive login only)
When a user logs out of an interactive session, the file ~/.bash_logout is executed if it exists.
The default value of the environmental variable, PATH, is set automatically using SoftEnv. See below for more information.
The file ~/.cshrc is used to customize the user's environment if his login shell is /bin/tcsh.
SoftEnv is a utility that is supposed to help users manage complex user environments with potentially conflicting application versions and libraries.
System Default Path
When a user logs in, the system /etc/profile or /etc/csh.cshrc (depending on login shell, and mirrored from csm:/cfmroot/etc/profile) calls /usr/local/packages/softenv-1.6.2/bin/use.softenv.sh to set up the default path via the SoftEnv database.
SoftEnv looks for a user's ~/.soft file and updates the variables and paths accordingly.
Viewing Available Packages
The command softenv will provide a list of available packages. The listing will look something like:
$ softenv These are the macros available: * @default These are the keywords explicitly available: +amber-8 Applications: 'Amber', version: 8 Amber is a +apache-ant-1.6.5 Ant, Java based XML make system version: 1.6. +charm-5.9 Applications: 'Charm++', version: 5.9 Charm++ +default this is the default environment...nukes /etc/ +essl-4.2 Libraries: 'ESSL', version: 4.2 ESSL is a sta +gaussian-03 Applications: 'Gaussian', version: 03 Gaussia ... some stuff deleted ...
The file ~/.soft in the user's home directory is where the different packages are managed. Add the +keyword into your .soft file. For instance, ff one wants to add the Amber Molecular Dynamics package into their environment, the end of the .soft file should look like this:
To update the environment after modifying this file, one simply uses the resoft command:
The command soft can be used to manipulate the environment from the command line. It takes the form:
$ soft add/delete +keyword
Using this method of adding or removing keywords requires the user to pay attention to possible order dependencies. That is, best results require the user to remove keywords in the reverse order in which they were added. It is handy to test out individual keys, but can lead to trouble if changing multiple keys. Changing the .soft file and issuing the resoft is the recommended way of dealing with multiple changes.
The following usage summary is lifted from the User's Guide:
Usage: uberftp [options] [host options] [host] uberftp [options] [host options] host cmds uberftp [options] srcurl dsturl uberftp [options] -f urlfile uberftp [options] -cmd url Note: Only the first usage creates an interactive session. host Connect to host. cmds This specifies the FTP commands to run once the control connection is establish. This list must be enclosed in quotes. Multiple commands are semicolon delimited. uberftp will execute these commands and then exit. srcurl and dsturl These denote the source URL and destination URL respectively. The accepted forms are: gsiftp://host[:port]/path ftp://[user[:pass]@]host[:port]/path file:path urlfile This file is a list of srcurl/dsturl pairs, one pair per line. Blanks lines and lines beginning with '#' are ignored. -cmd This will execute the given command using the url as the target. The supported commands and their syntax are listed below. The "host options" are: -P port Connect to port (default 2811 for GSI) -u user Specify the user to authenticate as. -p pass | X Use password 'pass' when authenticating with 'host'. If 'pass' equals 'X', read the password from STDIN with character echoing turned off. The "options" are: -active Use ACTIVE mode for data transfers. -ascii Use ASCII mode for data transfers. -binary Use BINARY mode for data transfers. -blksize n Set the internal buffer size to n. -cksum [on|off] Enable/Disable CRC checks after file transfers. -debug n Set the debug level to n. -family name Set the remote storage family to name. -glob [on|off] Enable/Disable filename globbing. -hash Enable hashing. -keepalive n Send control channel keepalive messages every n seconds during data transfers. -mode [E|S] Switch the transfer mode to extend block (E) or streams mode(S). -parallel n Use n parallel data channels during extended block transfers. -passive Use PASSIVE mode for data transfers. -pbsz n Set the data protection buffer size to n bytes. -prot [C|S|E|P|] Set the data protection level to clear (C), safe (S), confidential (E) or private (P). -retry n Retry commands that fail with transient errors n times. -resume path Retry the recursive transfer starting at path. -tcpbuf n Set the TCP read/write buffers to n bytes. -wait This will cause the client to wait for remote files to stage before attempting to transfer them. -v Print UberFTP version information and exit. Deprecated. -version Print UberFTP version information and exit. -versions Print version information about all used globus modules and exit. The supported "-cmds" are: -cat
Print to stdout the contents of the remote file. -chgrp [-r] group Set the group ownership on the remote object(s). -chmod [-r] perms Set the permissions on the remote object(s). -dir [-r] List the contents of the remote object. -ls [-r] List the contents of the remote object. -mkdir Create the remote directory. -rename Rename the remote object to the given . -rm [-r] Remove the remote object(s). -rmdir Remove the remote directory. -size Return the size of the remote object. -stage -r seconds Attempt to stage the remote object(s) over the time period given in seconds. Note: uberftp uses passive STREAMS mode by default.
