redirection

DNAx86 · #1 (**permalink**) 04-18-2008

Hi,

The code below works, it's a part of a bash shell script that serve to search a pattern $pattern_da_cercare in the files contained in a directory $directory_iniziale.

Now the proble is:
How can I redirect stderr to a file?
PS: so I want to redirect ALL the errors to a file.

I tryed to learn how to do it, but I haven't understood

Code:

find $directory_iniziale -type f | while read file 
do
  
  awk -v min=$MIN -v max=$MAX -v patt=$pattern_da_cercare '
  BEGIN{RS=" |\n"; patt = "(^|[^A-Za-z0-9])" patt "([^A-Za-z0-9]|$)" }
  $0 ~ patt {n++}
  END {
		if(n >= min && n <= max && n != 0) {print FILENAME " : " n}
  }
  ' "$file"

done

try this.....

yourscript 2>&1 > somefile

says take STDERR (2) and redirect to same place as STDOUT (&1)...

I inserted it in my script, but find still procude output errors on the screen and the error-file is empty

Code:

find $directory_iniziale -type f | while read file 2>&1 > conta_occorrenze_log.txt
do
  
  awk -v min=$MIN -v max=$MAX -v patt=$pattern_da_cercare '
  BEGIN{RS=" |\n"; patt = "(^|[^A-Za-z0-9])" patt "([^A-Za-z0-9]|$)" }
  $0 ~ patt {n++}
  END {
		if(n >= min && n <= max && n != 0) {print FILENAME " : " n}
  }
  ' "$file"

done

you want to put that on your command line, not within the script!

I only don't want that appear any errors on the screen.
