.TH X 1 .SH NAME x \- tools for dealing with alien systems .SH SYNOPSIS .PP .B x/mnt [ [ .I user@ ] .I host ] .PP .B x/run .RB [ -l ] .I cmd .PP .B x/vt .RB [ cmd ] .PP .B x/man .RI [ -b ] .RI [ man-flags ] .RI [ section ] .I title .PP .B x/path .B -lpPr [ .I path ] .SH DESCRIPTION .PP .I X is a collection of programs that tries to enable convenient interaction with alien systems of the UNIX® variety from the extreme comfort of Plan 9. .PP These programs rely on the namespace convention whereupon the root hierarchy of the remote system to be interacted with is mounted, usually through .IR sshfs (4), at the .IR mntgen (4) provided mountpoint under .I /n/x named after the .B user@host login tuple used to mount the system. .PP In this way the working directory of a program is loaded with two bits of information about the remote system: the login that can be used to access it, and the path relative to the remote root - which are exploited by the programs described here to provide some further convenience. .SH SETUP .PP Start .IR mntgen (4) with a mount point of .I /n/x somewhere convenient, perhaps in your profile: .EX ; mntgen /n/x .EE .SH COMMANDS .PP .B x/mnt is a convenience wrapper around .IR sshfs (4) that mounts the remote .I host as .I user to the appropriate place as discussed above. If .I user is missing, .B x/mnt tries the mount as both the invoking user and as .I root. If both the .I user and .I host are missing, it attempts to mount the system suggested by the current working directory. .PP .B x/run uses .B ssh(1) to connect to and run the .I cmd on the system suggested by the current path; .B cd(1) will be prepended to the command to execute it in the correct context. For example, given the current directory .B /n/x/me@moskvax/home/me/prog running .B x/run make will execute .B make(1) as user .I me on system .I moskvax in the .B /home/me/prog directory. .PP .B x/vt is similar to .B x/run except the .I cmd is run under the .IR vt (1) legacy teletype environment. If the .I cmd is missing a user's interactive $SHELL will be run. .PP .B x/man displays formatted manual pages from remote systems on its standard output. With .I -b the page is saved to a file and plumbed. .PP .B x/path extracts and prints the information embedded in the pathname of the working directory or the one given as the last argument. The options are as follows: .TF "-o option" .TP .I -l prints the login, i.e. the user@host string that can be used to connect to the remote system. .TP .IR -P , -p print the absolute (relative) path relative to the remote root. .TP .I -r prints the local path to the root of the remote hierarchy. .SH EXAMPLES .SH SEE ALSO .IR ssh (1), .IR vt (1), .IR mntgen (4), .IR sshfs (4) .SH SOURCE .B git://code.a-b.xyz/x .SH BUGS Mhm.
