UNIX for Dummies Questions & Answers

Hello,

I am interested in taking the output from a script i wrote and using it as input to a different script i wrote. So for example i want to take the output from program2 and use it as a parameter for program1. I didnt think i could use the >> symbols because i think that is just for .txt files. And i thought about piping the code from program1 into program2. However i dont really know how the syntax would look for a solution like this. So does anyone have a suggestion? Thanks.

it depends on your need, write an example that covers everything, then we can help you,

the simplest thing is to :

Code:

./script1 > output
./script2 `cat output`

you can get all args by $@ in your script2 code.

ok so this program greps the file $p for the parameter that the user enters and outputs some modified text with sed.

grep $1 $p|sed s/.*=.//|sed 's/<.*//'


this program greps the parameters the user enters in the file $q and cuts out a certain column that i want

grep "$*" $q|cut -c77-78


now what i want to do is take the output from the second program and use it as the parameter in program 1. Make sense?

so if the command1 is :

Code:

 grep $1 $p|sed s/.*=.//|sed 's/<.*//'

and command2 is :

Code:

 grep "$*" $q|cut -c77-78

and you want to grep the command1's result in command2:

Code:

 grep "`grep $1 $p|sed s/.*=.//|sed 's/<.*//'`" $q|cut -c77-78

so you can merge them into one command.

i want to use command2 result in command 1. so the part in double quotes would be command 2
