Ksh is my default shell, but I want use the bash shell since its convenient to me.
When I type a long command line in a terminal, it does not wrap to the next line when I reach the end of the line and it wraps onto the same line, overwriting my prompt and the rest of what I typed.
I searched in the Unix and internet, all problem solved by modifying the customized PS1 command but I don't have any customized prompt I am using default one.

I'm using a barcode scanner to grab ISBNs. Unfortunately, short of hitting "enter" each time (not easy while on a ladder), there's no good way to split it up. So I scanned it into a series of long lines in notepad.
Now, I need to split each line into 12-number lines.

Greetings!
Some of my files list hardware errors (we test electronic components), some have none. If the file name has no errors, I still want to display a message like "No error", else I display the error from the file itself.

Greetings fellow scripters.
I find myself editing multiple files, sometimes with the same bits of information. My bash script, a changelog, and a plist file (OS X). Once I realized this, I thought why not script part of this process (and so it begins). In any case, I've solved several of the... (1 Reply)

I've used the system function in C to call bash commands before, but wanted to learn this way too. The solution in the book worked perfectly. However, I tried changing the simple "ls -l... (3 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.
