It would be helpful if someone could help me out here. The problem I have been having is that I cannot run some commands which are valid - whenever I try to run the command I get the message "command not found". Now, if I run the same command as root it executes. These commands do not have to be... (5 Replies)

I can't get this to work. Running a single command works fine:
find . -name "*.dat" -exec wc -l '{}' \;
gives me the file name and number of lines in each .dat file in the directory.
But what if I want to pipe commands, e.g. to grep something and get the number of lines with that pattern... (3 Replies)
Hi Gurues,
I need to modify an existing script that uses find to search a folder, and then move its contents to a folder. What I need to do is run gzip on each file after it's moved.
So, I ran this little test:
Put a ls.tar file on my $HOME, mkdir tmp, and then:

Hi Folks -
Is there a way to add two execs to one script? For instance, I need to redirect the stdout and stderr to two separate directories. I want to do this:

exec 2>"/new/path/file.err" >... (7 Replies)

sb2-show
sb2-show(1) sb2-show man page sb2-show(1)NAME
sb2-show - sb2 diagnostics tool
SYNOPSIS
sb2-show [-b binary_name ] [-m mode ] [-f function ] [-D ] [-v ] command [parameters]
DESCRIPTION
sb2-show is a tool for querying and testing what scratchbox2 does "behind the scenes".
The two most common uses are testing path mapping (commands path and which ) and finding out how programs are executed (the exec command).
Additionally, there are some commands that are intended to be used internally by scratchbox2 itself, and not so useful for a normal user.
sb2-show must be executed inside a scratchbox2 session (see sb2(1) for details about creating sessions)
COMMANDS
Common commands:
path [path1] [path2] [pathN]
Show mapping results for listed pathnames
which [path1] [path2]..
Show mappings of pathnames, a less verbose variant of the path command (useful when using sb2-show from scripts)
exec program_path [arg1] [arg2]..
Show how a program would be executed, together with environment modifications.
realcwd
Show real current working directory (Inside a session /bin/pwd will usually report virtual paths, and this is the only way to deter-
mine the real wroking directory).
Commands for non-interactive use and debugging of scratchbox2:
exec-cmdline file [argv1] [argv2]..
show execve() modifications on a single line (does not show full details, useful when using sb2-show from scripts)
log-error 'message'
Add an error message to the logfile
log-warning 'message'
Add a warning message to the logfile
verify-pathlist-mappings required-fix [ignorelist]
Reads list of paths from stdin and checks that all paths will be mapped to a required prefix. This is used by sb2-check-pkg-map-
pings, (an internal utility).
execluafile filename
Load and execute Lua code from file.
binarytype realpath
detect & show type of program at realpath (which is an already mapped path)
var variablename
show value of an internal string variable
libraryinterface
show preload library interface version (the Lua <-> C code interface)
qemu-debug-exec file argv0 [argv1] [argv2]..
show command line that can be used to start target binary under qemu gdbserver
OPTIONS -v verbose.
-b binary_name
show using binary_name as name of the calling program
-f function
show using function as callers name (full name of library or system call)
-D Ignore directories while verifying path lists (effective only for the verify-pathlist-mappings command)
-t report elapsed time (real time elapsed while executing the command)
-x file
Load and execute Lua code from file before executing the command. Useful for debugging and tuning lua scripts of sb2.
-X file
Load and execute Lua code from file after executing the command. Useful for debugging and tuning lua scripts of sb2.
-g port
use port as qemu gdbserver listening port (default port is 1234). See command qemu-debug-exec
EXAMPLES
Show where the /etc directory gets mapped:
$ sb2 sb2-show path /etc
/etc => /opt/maemo/tools/etc (readonly)
(exact results depend on how sb2-init was executed; what mapping mode is the default, etc.)
Typically, home directories are not mapped:
$ sb2 sb2-show path /home/yourname
/home/yourname => /home/yourname
In development modes, host-compatible versions of tools are executed:
$ sb2 sb2-show exec /bin/ls
File /bin/ls
Mapped /opt/maemo/tools/bin/ls (readonly)
argv[0] /bin/ls
...
But in the emulation mode, only target's executables are used. Try also:
$ sb2 -e sb2-show exec /bin/ls
