Bash Script Issues (If statement for file copying)
Writing a bash script for use with Geektool, pulls the battery info, and shuffles images around so that an Image geeklet can display the correct expression as the desktop background. (Eventually I intend to make it more intricate, based on more variables, and add more expressions)
I'm extremely new to the language, but the script below did return a result the first time I ran it through Geektool. The only problem is that the variable did not match the result (batt at 95%, result was for 5% and below). It stopped working after that.
The percentage display works every time, but that's most likely because I didn't write that part of the script, I scavenged it. I'd rather use a variable than rerun the calculation over and over, but I couldn't get it to work.

I have one file "file.a.b.c-d.r" that I would like to use to spawn 4 other files:

where the field "c-d" changes into my 1 and A-D.

The bash stores each uniqueid in an array and then passes them to %q to get the unique path. That seems to work what I am having trouble with is renaming each .png with the unique value in %q. I thought it was working but upon closer inspection, a .png file is being sent to scp.... but only 1 and... (21 Replies)

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
