Question Foreach issue
Hello,

I found that this foreach should work with two lists (source: Wikipedia.org)
Code:
foreach i {1 2 3} j {a b c}  {   puts "$i $j"}

==
I try smth. like:
With two text files:
first.part
second.part
Code:
 
foreach first (`cat first.part`) second (`cat second.part`)
toolcommand $first -toolcommand $second
end




TCSH is used.

Also script solutions are welcome, like save line x in first.part and line x in second.part to two vars and use them later...

Thanks

Code:
set valf=`cat first`
@ num=1
foreach vals ( `cat second` )
toolcommand $valf[$num] ; toolcommand $vals
@ num++
end

regards

Thanks for the fast response.
Nearly what I wanted.

But this puts the complete file into the first var and prints always the complete first var and not just the related lines.

Quote:
File1:
A
B
C
File 2:
1
2
3
Quote:
Your Output:
A B C1
A B C2
A B C3
^^ Prints A B and C always.

My wanted output
A1
B2
C3
Used code:
Code:
#! /bin/tcsh -f
set valA=( `cat first` )
@ num=1
foreach valB ( `cat second` )
  echo "$valA""$valB"
  @ num++
end

Issue is, that you assigned the complete "cat FileONE" to your var outside of the loop.
This is why i wanted to use these foreach with two lists. But other working solutions are also welcome.

Thanks

Code:
awk 'NR==FNR{a[++i]=$0;next}{b[++j]=$0}END{for(k=1;k<=j;k++){print a[k]b[k] }}' file1 file2

Thanks,
can you show me how i can use now this in a script with usage of the vars? (nawk BEGIN usage?)

I want to use each element for my commands.

so for example like:
Code:
 
echo This is first line from file1 "varA[$1]" and this is the corresponding line from file2 "varB[$2]"

In your example I want to use in my script these vars: a[k]b[k]
Just don't know how to access them in the script (how to run your awk command there)

Still not able to get the wanted result... hanging still on the print issue...

With paste and without does not print out what I want...
with paste I do not see any other printouts as the files
Code:
#!/bin/sh
awk 'NR==FNR\
{
  a[++i]=$0;next
}
{
  b[++j]=$0;
}
END\
{
  for(k=1;k<=j;k++)
    {
      print COMMAND
      print a[k]
      print ("COMMAND_OPTION")
      print b[k]
    }
}' | paste file1 file2

^^ i see no COMMAND and neither COMMAND_OPTION ^^
Tried with one print and multiple
Tried with one printf and usage of both %s
with double quotes and single quotes - with brakets and w/o...
don't know why I do not see my wanted printout.

i want to get:
Quote:
COMMAND line1_form_file1 COMMAND_OPTION line1_from_file2
COMMAND line2_form_file1 COMMAND_OPTION line2_from_file2
COMMAND line3_form_file1 COMMAND_OPTION line3_from_file2
Thanks

^^ The print a[k]b[k] } does not work

a[k] is EMPTY
b[k] contains the information from both files!
