Top Forums Shell Programming and Scripting Can I use columns from text files in if statements? Post 302476847 by webkid on Thursday 2nd of December 2010 05:20:03 PM

This is what I will do:
Code:
df -k /home/* | grep -v "Filesystem"|awk '{print $3, $4, $1}' > dfcap.txt

echo -n "Enter the size (in kilobytes) you wish to check against all user capacities: "
read cap

cat dfcap.txt | while read USED AVAIL FNAME
do
     if ($USED -gt $cap )
          echo $1 -- [all used capacities above inputted variable]
     else
          echo $1 -- [no one has a file usage above this size]
     fi
done

You may compare it with USED or AVAIL by changing the variable.

LEARN ABOUT FREEBSD

colrm

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME

     colrm -- remove columns from a file

SYNOPSIS

     colrm [start [stop]]

DESCRIPTION

     The colrm utility removes selected columns from the lines of a file.  A column is defined as a single character in a line.  Input is read
     from the standard input.  Output is written to the standard output.

     If only the start column is specified, columns numbered less than the start column will be written.  If both start and stop columns are spec-
     ified, columns numbered less than the start column or greater than the stop column will be written.  Column numbering starts with one, not
     zero.

     Tab characters increment the column count to the next multiple of eight.  Backspace characters decrement the column count by one.

ENVIRONMENT

     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).

EXIT STATUS

     The colrm utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     awk(1), column(1), cut(1), paste(1)

HISTORY

     The colrm command appeared in 3.0BSD.
