Q1 Do some research on shell programming on the web You will probably realise your mistakes. (I am assuming you are using BASH - I am not sure of the syntax in other shells)
Q2 Try awk. Read "NR" lines from second file (one with replacements), use the string to modify $0 gawk may have a simpler/cleaner soln,. but it wont be compatible On Sun, Jan 18, 2009 at 13:31, Prashant Batra <[email protected]>wrote: > > #$1 is the file in which contains text to be replaced > #$2 is the file which contains the text with which it is to be replaced > > filename=$1 > pattern=$2 > > lines=`wc -l $2|cut -d' ' -f1` > > for i in `seq 1 $lines` > do > > replacewd=`head -$i $2 | tail -1` #read line by line > echo $replacewd > head -$i $1 | tail -1 > temp #write each line $1 in temp > file > sed "s/2u/${replacewd}u/" temp >> output #replace 2 and append > the output in output file > > done > > This could be one of the solution... > but its not very general > > cheers > Prashant Batra > > > > > > On 1/18/09, Prashant Batra <[email protected]> wrote: > > filename=$1 > > lines=`wc -l $filename|cut -d' ' -f1` #finds no of lines in the file > > echo "no of lines in the file are $lines" > > declare -a array[2] > > for i in `seq 1 $lines` > > do > > echo $i > > array=`head -$i $filename | tail -1` > > echo $array > > done > > > > > > This could be helpful > > but the problem is that the value of array does not persist outside the > > loop. > > hope someone else could provide the answer. > > > > On 1/18/09, Sharad Birmiwal <[email protected]> wrote: > >> > >> Hi, > >> > >> I'm not gonna fix any code but I'll help you with whatever I can.. > >> > >>> I don't know how many lines are present in the file. > >> > >> use "wc -l" for this > >> > >>> Q2) > >>> > >>> I have the following content on a file.I need to replace '2' in each > line > >>> with a different value which are present in a file > >> > >> Looks like a complicated operation.
