Column for unix - Page 2

kevin55 · #1 (**permalink**) 09-29-2008

the column utility takes input and formats it into columns (three columns as defualt i think) but its only in linux, not in unix. i know there are a few regular commands i can use to make a simple script to use it in unix, i just dont know the one command that could format it. would it be fmt

column uses environment variable COLUMNS as a definition of the width of the output in characters ( example 80 ) unless -c is specified.

Java? That's an awk script.

Could could put it on one line and use no comments and shorter variable names if you wish, e.g.

Code:

ls | awk 'BEGIN{if(!(w>0))w=80}length>m{m=length}{a[NR]=$0}END{c=int(w/++m);for(i=1;i<=NR;i++){printf("%-"m"s",a[i]);if(!(i%c))print""}if(--i%c)print""}'

You could implement the same algorithm easily enough in pure shell code or perl if you preferred.

You may be thinking of something like ls | paste - - - - (to format ls output into four columns, but that won't adjust the column widths to make them line up.

Please help me in troubleshooting my problem in Samba?
I tried to instal Samba 3.0.24 in our SCO UnixWare 7.1.4 but after installing the nmbd daemon is not running.
When i check the syslog from /var/adm, the following error appears:
Sep 30 13:04:22 unixeei nmbd[25169]: bind failed on port 137 socket_addr =0.0.0.0.

Thanks

Eric
