"Create a shell script that changes the selected word to another word in all files from selected archive. The script has 3 parameters: archive, old-word, new-word."
2. Relevant commands, code, scripts, algorithms:
This is a begginer's level exercise, we were instructed to use simple solutions such as loops
3. The attempts at a solution (include all code and scripts):This was my attempt:
Code:
for filename in *
do
sed "s/old-word/new-word/g" "$filename" >temp
mv temp "$filename"
done
My TA told me this but I believe I could not understand how to do that: "you should make an error-proof script that does not overwrite any file. If I
would have a file called 'temp', you will overwrite it. The same will happen if
two people will run your script simultaneously.
It should work with commandline parameters also. In case of any error it
should report the error to standard error output.
Perform testing on filenames (inside the archive, archive name, directory
names) containing spaces."

AMARCHIVER(8) System Administration Commands AMARCHIVER(8)NAME
amarchiver - Create, extract or list amanda archive
SYNOPSIS
amarchiver --version|--create|--extract|--list [--verbose] [--file file] [filename]...
DESCRIPTION
Amarchiver manipulates amanda archive file. On creation, amarchiver doesn't recurse into directories. If a filename specifies a directory,
it will be ignored. If it specifies a character device, amarchiver reads the device and archives the data. If a filename specifies a named
pipe, amarchiver reads the named pipe and archives the data.
Note that this tool is more limited than the Amanda archive library, and may not be appropriate for some archive files -- particularly
those which use non-strings in their filenames.
OPTIONS --version
print the amarchiver version
--create
Create an amanda archive. Only the supplied filenames are included. With one --verbose, lists the filenames. With two, lists the
filenames and sizes.
--list
List the filenames in an amanda archive. No additional filenames are allowed on the command line.
--extract
Extract an amanda archive. If filenames are supplied, only those files are extracted. Files are created in the current directory,
suffixed with a dot ('.') and the attribute ID.
--verbose
Give more information.
--file file
Create, list or extract from the given file instead of stdin/stdout.
