Bash: extracting 2 strings from 1 line

Hi everyone.

I am very new in bash scripting (and scripting at all).

I've got lines like these:
Code:
-rw-r--r-- 1 setub 1049089 27M mars  13  2017 arch_amiel_038g_f016r.tif
-rw-r--r-- 1 setub 1049089 584K juin   9  2008 arch_amiel_composition.jpg

I wish to extract 2 string types so that I can get:
Code:
27M[separator]arch_amiel_038g_f016r.tif
584K[separator]arch_amiel_composition.jpg

I used sed -d to try first to delete "-rw-r--r--" but I was discouraged soon, co's I couldn't find the way out of deleting also the "r" of the expressions "arch_amiel_038g_f016r.tif" and "arch_amiel_composition.jpg".

If you have an easy solution to get what I wish (the 2 lines above) or some suggestion to go forward...

Thanks a lot!!! Smilie

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. SEE ALSO
