    Nope...

    def=0;
    for( i in s ) {
    ... dostuff
    def=def+1;
    }

    Init def to zero previous to loop, increment each loop iteration

    I am seeing that def is a random appearing value mod(max loop iterations=lines) that bears no discernible relationship to the data (i value for file line n) at any particular loop iteration.

    def is NOT constant, it just does not appear to bear any relationship to line #

    Aargh.. can't figure this out: for( i in s), index
    Following is a script file snippet which is intended to replace a keyword with another string, which contains a numeric (line #) index into a key word file of following form: keyword;replacetext ... keyword_n;replacetext_n It parses all *.htm files in a directory, parses and creates equivalent *.htp files. Parsing and replacement works fine. #!/bin/sh INEXT="htm" OUTEXT="htp" ... ParseKeys() { # $1 = KeyWordFile find . \( ! -name . -prune \) -type f -name "*.$INEXT" | while read FILE do awk 'BEGIN{ FS=";"} FNR==NR{ s[$1]=$2; next } { def=0; for( i in s ) { system("echo hello alldef: " def " i: " i " >>trash.txt") if( $0 ~ i ){ system("echo hello def: " def " >>trash.txt") system("echo hello i: " i " >>trash.txt") system("echo hello s[i]: " s[i] " >>trash.txt") gsub(i,s[i]) } def=def+1; } print $0 }' $1 $FILE > temp # $FILE is form ./*.htm outfile=`echo "$FILE" | cut -f2 -d "/" | cut -f1 -d "."` echo "$outfile" mv -f temp $outfile.$OUTEXT done echo hello } The problem is that my line counter (def) for the keyfile is out of sync with the keyword (iterator - i) from "for( i in s )" I get output like: hello alldef: 0 i: blue_pill which should be: hello alldef: 32 i: blue_pill since blue_pill is on the 32nd line. does the "for( i in s )" not start iterating at first line, or am I seriously missing something? Is there a better way to do this? Thanks for looking... Bill

    Following is a script file snippet which is intended to replace a keyword with another string, which contains a numeric (line #) index into a key word file of following form:

    keyword;replacetext
    ...
    keyword_n;replacetext_n

    It parses all *.htm files in a directory, parses and creates equivalent *.htp files. Parsing and replacement works fine.
    #!/bin/sh

    INEXT="htm"
    OUTEXT="htp"
    ...
    ParseKeys()
    {
    # $1 = KeyWordFile
    find . \( ! -name . -prune \) -type f -name "*.$INEXT" | while read FILE
    do
    awk 'BEGIN{ FS=";"}
    FNR==NR{ s[$1]=$2; next }
    {
    def=0;
    for( i in s ) {
    system("echo hello alldef: " def " i: " i " >>trash.txt")
    if( $0 ~ i ){
    system("echo hello def: " def " >>trash.txt")
    system("echo hello i: " i " >>trash.txt")
    system("echo hello s: " s " >>trash.txt")
    gsub(i,s)
    }
    def=def+1;
    }
    print $0
    }' $1 $FILE > temp
    # $FILE is form ./*.htm
    outfile=`echo "$FILE" | cut -f2 -d "/" | cut -f1 -d "."`
    echo "$outfile"
    mv -f temp $outfile.$OUTEXT
    done
    echo hello
    }

    The problem is that my line counter (def) for the keyfile is out of sync with the keyword (iterator - i) from "for( i in s )"

    I get output like:

    hello alldef: 0 i: blue_pill

    which should be:

    hello alldef: 32 i: blue_pill

    since blue_pill is on the 32nd line.

    does the "for( i in s )" not start iterating at first line, or am I seriously missing something? Is there a better way to do this?

    Thanks for looking...
