print selected lines

[tonivm]

Hi everybody:

Hi everybody:
I try to print in new file selected lines from another file wich depends on the first column.

I have done a script like this:

lines=( "1" "2" "3" "4" "5" "6" "7" "8" "9" "10" "11" "21" "31" "41" "51" "55" "57" "58" )
${lines[@]}
for lines in ${lines[@]}
do
  awk -v  target=$lines  ' if(NR == target) {print $0} ' file1 >> file2
done

But I have the next error:

/T-eff.sh: 42: Syntax error: "(" unexpected ------ where the line 42 correspond when I declare the array "lines"

Any suggestion?. Thanks in advance.

[gray]# You use bash, right ? Will not work in ksh.[/gray]
lines=( "1" "2" "3" "4" "5" "6" "7" "8" "9" "10" "11" "21" "31" "41" "51" "55" "57" "58" )

[gray]# Why this line ? Remove it.[/gray]
[gray]# [red]${lines[@]}[/red][/gray]

[gray]# Use distinct identifiers. This is not Perl.[/gray]
for [red]line[/red] in ${lines[@]}
do
  awk -v  target=[red]$line[/red]  ' if(NR == target) {print $0} ' file1 >> file2
done

Hi:
Thanks for your reply.

# You use bash, right ? ---- Yes I do. 
# Will not work in ksh.
lines=( "1" "2" "3" "4" "5" "6" "7" "8" "9" "10" "11" "21" "31" "41" "51" "55" "57" "58" )

# Why this line ? Remove it.
# I did it now.
# ${lines[@]}

# Use distinct identifiers. This is not Perl.
# Of course, I changed it.
for line in ${lines[@]}
do
  awk -v  target=$line  ' if(NR == target) {print $0} ' file1 >> file2
done

But I have the same error.

awk -v target=$lines 'NR == target' file1 >> file2

Thakns a lot for replies. I have solved the problem.

At the begining of the script, I have changed:

#!/bin/sh

for

#!/bin/bash

And now, it works correctly. Best regards for everybody.

Hi

Ah. I would like to say that I looked at the evident errors first... But as futurelet's reply shows, in fact I missed the evident one...
