Top Forums UNIX for Dummies Questions & Answers Excluding a specific column from sed replacement Post 302755009 by Corona688 on Friday 11th of January 2013 03:38:50 PM

sed does not understand what a column is.

Your best bet would be to use a language like awk, which understands what a column is.

You'd be better served learning the awk language than asking endless questions which are trivially answered in it...

Code:
awk '{ for(N=1; N<=NF; N++) { if(N==3) continue; if($N == "0") $N=1 } 1' inputfile

The column utility formats its input into multiple columns. Rows are filled before columns. Input is taken from file operands, or, by default, from the standard input. Empty lines are ignored. The options are as follows: -c Output is formatted for a display columns wide. -s Specify a set of characters to be used to delimit columns for the -t option. -t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the characters supplied using the -s option. Useful for pretty-printing displays. -x Fill columns before filling rows. ENVIRONMENT
The COLUMNS, LANG, LC_ALL and LC_CTYPE environment variables affect the execution of column as described in environ(7). EXIT STATUS
The column utility exits 0 on success, and >0 if an error occurs. EXAMPLES
(printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; printf "HH:MM/YEAR NAME " ; ls -l | sed 1d) | column -t SEE ALSO
