how to export a pipe variable directly to shell command

Hi
I am working on a project to grep/awk/sed a file and directly process a command between two expressions.

for instance if the file reads

XXXXXXXX YYYYY ZZZZZ
firstmatch
du -h /home  
secondmatch
AAAAA BBBBBBB CCCC

I can extract the information I need (du -h /home) but can not make it run directly in a shell

sed '1,/firstmatch/d;/secondmatch/,$d |

I just end up with

Hi ozo
Not sure what your suggestion is.
isn't the command 'file' just for determining a file type?

I can export the sed result to a file with
sed '1,/firstmatch/d;/secondmatch/,$d'  > /home/testfile.sh
and then run it, but I was hoping to just output and run a single command directly

ozoCommented:
file was meant to be the name of your file containing
XXXXXXXX YYYYY ZZZZZ
firstmatch
du -h /home  
secondmatch
AAAAA BBBBBBB CCCC


you can output to a file with > /home/testfile.sh
but where are you telling sed where to get the input from?

doesn't xargs with no utility specified default to  | xargs echo

`sed '1,/firstmatch/d;/secondmatch/,$d'  /path/to/your/file`
or
$(sed '1,/firstmatch/d;/secondmatch/,$d'  /path/to/your/file)
should execute the command directly

Ah yes, correct ozo.

Meant to write

sed '1,/firstmatch/d;/secondmatch/,$d'  /path/to/your/file | bash

That could be better than `` or $() if there are multiple commands between your expressions

You can also call it eplicitly like this, supposing your shell is bash:

bash -c "$(sed '1,/firstmatch/d;/secondmatch/,$d' /path/to/your/file)"

Thanks Guys

sorry my typo in the above expressions I accidentally omitted my source file, it should have read  
sed '1,/firstmatch/d;/secondmatch/,$d'  /home/testfile.txt|

all accepted solutions worked well, I also experimented and tried the below as an alternative, it worked also.

sed '1,/firstmatch/d;/secondmatch/,$d'  /path/to/your/file | sh  

cheers
