* hush: allow to run interactive shell in do_shSascha Hauer2012-04-301-1/+1
| | | | | | | This allows to call 'sh' in scripts without arguments in which case an interactive shell will be started. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* hush: Fix globbingSascha Hauer2012-04-301-48/+79
| | | | | | | | | | | | | | | | | hush has a long standing and anoying glob bug. hush expands wildcards during parsing of the script or command stream. When the command stream begins to execute the wildcards are already expanded which leads to: mkdir /tmp cd /tmp mkdir foo; ls * ls: *: No such file or directory To fix this expand wildcards right before executing the command. Since 'for' loops are not executed in commands, we have to keep the old behaviour in here so that 'for i in *' still works. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* hush: pass GLOB_NOCHECK to globSascha Hauer2012-04-301-6/+1
| | | | | | | By doing so glob will not return GLOB_NOMATCH anymore but instead just does what fake_glob would do. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* hush: simplify globhackSascha Hauer2012-04-301-31/+8
| | | | | | | | | | | | | | | | hush used to escape '*' '[' '?' during parsing because the quotes got removed in the first parsing loop. globhack is used to remove these escapes again for glob. Since we now keep the quotes until the end of parsing and we no longer escape glob wildcards, we do no longer have to remove any quotes. With this globhack can be much simpler. While at it, change the prototype to match the one from glob() and rename the function to fake_glob, because that's what it is: it just copies the input string into the output struct without actually globbing.

* hush: remove quotes at end of processingSascha Hauer2012-04-301-23/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hush removes the quotes from strings too early. This leads to some bugs. When hush executes echo "hello sascha" it correctly results in: argv[0] = "echo" argv[1] = "hello sascha" However, the following behaves incorrect: a="hello sascha" echo "$a" results in: argv[0] = "echo" argv[1] = "hello" argv[2] = "sascha" This is because hush removes the quotes and inserts variable values in a single loop, so echo "$a" becomes: echo hello sascha after the loop. Instead, keep the quotes until all variables are inserted and remove them at the end. This also fixes that echo \" resulted in \" instead of ". Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the scripts/mkcompile_h from the Kernel. This gives us additional information about the build like who built this binary and with which compiler. Currently the only information used is the build timestamp and the generation number. This also fixes the build timestamp in the banner which is now correct even with consecutive builds without making clean in between. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | command: do not allow abbreviated commands anymoreSascha Hauer2012-02-271-19/+3
|/ | | | | | | | | | | | abbreviated commands are derived from U-Boot and are only partly useful. Noone expects from a shell to support this, also we have tab completion. They also have some funny side effects. For example we have a 'time' command. If this command is not compiled in, the time command is interpreted as an abbreviated version of the 'timeout' command. So remove support for abbreviated commands and safe the binary space. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* getopt: save and restore contextSascha Hauer2012-02-272-9/+18
| | | | | | | | | | | | execute_command is the single point where commands are executed and thus a new getopt context is needed. currently we call getopt_reset here to reset the context. This breaks though when a command tries to run a command itself by calling execute_command or run_command. In this case we have to store the context and restore it afterwards. The same is necessary in builtin_getopt. Currently noone does this so this one shouldn't fix a bug, but merely allows us to do such things later. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

The FAT driver often accesses the fat and then data again, which currently can't be cached. Reimplement this with a list of cached chunks.
