Top Forums Shell Programming and Scripting How to check the file size in a dir Post 302242435 by era on Thursday 2nd of October 2008 02:17:07 AM

The error message appears unrelated to your script.

As an aside, the first ls is Useless. You might want to use stat instead of ls in order to get easily machine-parsed file sizes.

Also, you seem to have a complex of syntax errors before the "then". You need spaces inside the square brackets, a semicolon before the "then", and a dollar before the parentheses.

Code:
for f in *
do
  if [ $(ls -l "$f" | awk '{ print $5 }') -gt $1 ]; then
    echo "$f"
  fi
done

The following is somewhat more succinct:

Code:
ls -l | awk -v size=$1 '$5 > size { print substr($0,55) }'

(though I get my file names starting in column 48, not 55). If your awk doesn't understand -v you can see if you have mawk or nawk or gawk instead.

NAME
cut - select out columns of a file SYNOPSIS
cut [ -b | -c] list [file...] cut -f list [-d delim] [ -s] OPTIONS
-b Cut specified bytes -c Select out specific characters -d Change the column delimiter to delim -f Select out specific fields that are separated by the -i Runs of delimiters count as one -s Suppres lines with no delimiter characters, when used EXAMPLES
cut -f 2 file # Extract field 2 cut -c 1-2,5 file # Extract character columns 1, 2, and 5 cut -c 1-5,7- file # Extract all columns except 6 DESCRIPTION
[file...]" delimiter character ( see delim)" with the -f option. Lines with no delimiters are passwd through untouched" Cut extracts one or more fields or columns from a file and writes them on standard output. If the -f flag is used, the fields are sepa- rated by a delimiter character, normally a tab, but can be changed using the -d flag. If the -c flag is used, specific columns can be specified. The list can be comma or BLANK separated. The -f and -c flags are mutually exclusive. Note: The POSIX1003.2 standard requires the option -b to cut out specific bytes in a file. It is intended for systems with multi byte characters (e.g. kanji), since MINIX uses only one byte characters, this option is equivalent to -c. For the same reason, the option -n has no effect and is not listed in this man- ual page. SEE ALSO
