Here we go again analysing FASTA-files. I wonder if we are going to be mentioned in the dozens of biological research papers we have helped to create over time.

First: you come across like a teacher posing the homework for us. Actually we are all professionals here and have done our homework meticulously which is why we don't have to do more homework any more. In case it was homework given to you by your teacher: there is a special forum for this with special rules in place. Please re-create the thread there and provide the necessary information.

Second, in case this is not homework but actually your work: we do not insist on a lot of social conventions here (after all, we are sysadmins - being somewhat autistic is part of the requirement for this job), but still a well-placed "please" here and there, along with some of the common niceties called "good manners" oils the social machinery. If you ever wonder who writes the answers to your questions: it is not some clever machine and a fat server - it is actually living, breathing persons.

Third and foremost: we are here to help you help yourself. If you want a shell-script - WRITE IT! Attempts, however failing, will count. If you tried and it didn't work, post what you did and the error you got trying to run it. We will, regardless of how long it will take, explain to you what was wrong and how to do it better (actually quite like the way i explain to you right now why you need to change your problem statement) until you understand. We will also point out ways to better solve the problem, different tools, suggest sources to find valuable information and so on and so on. But we will NOT write your code for you. We are a help forum, not your unpaid programming staff.

I hope this helps.

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. SEE ALSO
