Problem using awk

Question

I have a problem using awk. Print, from every file given as a parameter, the number of line that has the length at least 10. Also, print the content of that line(s), except the fist 10 characters. At the end of the analysis of a file print the name of the file and the number of lines printed.

This is what I've done so far:

{
if(length($0)>10)
{
 print "The number of line is:" FNR
 print "The content of the line is:" substr($0,10)
 s=s+1
}
x= wc -l //number of lines of file
if(FNR > x) 
{
 print "This was the analysis of the file:" FILENAME
 print "The number of lines with characters >10 are:" s
}
}

This prints the name of the file and the number of lines after every line that has at least 10 characters but I want something like this:

print "The number of line is:" 1
print "The content of the line is:" dkhflaksfdas
print "The number of line is:" 3
print "The content of the line is:" asdfdassaf
print "This was the analysis of the file:" awk.txt
print "The number of lines with characters >10 are:" 2

Try something like this:

#!/usr/bin/gawk -f
{
    ## Every time we change file, print the data for
    ## the last file read (ARGV[ARGIND-1])
    if(FNR==1 && ARGIND>1){
        print "This was the analysis of file:" ARGV[ARGIND-1]
        print "The number of lines with >10 characters is:" s,"\n"
        s=0;
    } 
    if(length($0)>10){
        print "The line number is:" FNR
        print "The content of the line is:" substr($0,10)
        s=s+1   
    }
}
## print the data collected on the last file in the list
END{
    print "This was the analysis of file:" ARGV[ARGIND]
    print "The number of lines with >10 characters is:" s,"\n"
}

If you run this on the files a, b and c:

$ ./foo.awk a b c
The line number is:2
The content of the line is:kldjahlskdjbasd
This was the analysis of the file:a
The number of lines with characters >10 is:1 

The line number is:2
The content of the line is:ldjbfskldfbskldjfbsdf
The line number is:3
The content of the line is:kfjbskldjfbskldjfbsdf
The line number is:4
The content of the line is:ldfbskldfbskldfbskldbfs
The line number is:5
The content of the line is:lsjdbfklsdjbfklsjdbfskljdbf
This was the analysis of the file:b
The number of lines with characters >10 is:4 

The line number is:1
The content of the line is: asdklfhakldhflaksdhfa
This was the analysis of the file:c
The number of lines with characters >10 is:1 

Answer 2

you can put your end-of-file summary in an END {...} block - it will get executed as the script exits.

i.e. get rid of the bogus x=wc -l and change the if (FNR > x) { ... } to just END { ... }
