Once I extract... (4 Replies)
How can I direct awk output to go nowhere? I can write the data to a file easy enough or print it on the screen. But for this particular command I don't actually want the data and I don't want to create a file. I just want the data discarded.
Thanks in advance (3 Replies)
Hello everyone, I've suddenly gotten very interested in sed and awk (and enjoying it quite a bit too) because of a large conversion project that we're working on.

In the awk below the first sample MEV45 gets extracted from the html, but the subsequent MEV46 and MEV47 do not as they are not part of parse. I can not seem to add them to the code. Thank you very much @RudiC your awk is very nice :).

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 filename 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.
