Hi All

i am writing a shell which would read from a parameter file , and once the file is read it should not display those lines in the output file

Example

Prameter file is b.txt and it contains the following :
aaaa
cccc
ffffff
rrrrrr
qqqq

and i issue the command df -d it will display all the datas and store it in a log file , but those lines which are mentioned should not be there in the log file
can anyone help me on this

something like this,

awk 'BEGIN{ while ( getline < "parameter.file" ) { arr[$0]++ } }{ if ( !( $0 in arr ) ) { print } }' data.file

one quick question : data.file which is mentioned is the output log file which is generated ?

Thanks

exactly

and the paramter.file is the "b.txt"

Hi , Thanks fo you help

I am rewritting the requirement once again

i am executing a command autorep -j % and redirecting the ouput to one file

autorep -j % -q > data1.txt

data1.txt has all the information which is avaiable in the database

and have a parameter file which has these lines (b.txt)
qqqqq
aaaa
asss
assddd
454545

Once i run the shell script with the command included

autorep -j % -q > data1.txt , it should read from the parameter file and should produce another output data2.txt , and those ouput should not have the lines which are in b.txt

Can anyone help me on this !!

Thanks once again
