How to get du -ksh working without a carriage return in shell-scripting?

manpreet Best Answer 2 years ago

Working on a script to fit a specific format. I need the results of the command to be echoed between pipes | X |.

When I try to use du -ksh it always brings a carriage return.

Any idea how to deal with it?

#!/bin/bash
echo -e "|_. Sites-enabled |_. ServerName |_. ServerAlias |_. UserID |_. DocumentRoot |_. Dig ServerName |_. Dig ServerAlias |"
ls /etc/apache2/sites-enabled/* | while read fichier

do

# SiteName & ServerName & ServerAlias & UserID
    sitename=($(echo $fichier | cut -d"/" -f5))
    serverName=`awk -F"ServerName" '/ServerName/{printf "%s ",$2}' $fichier`
    serverAlias=`awk -F"ServerAlias" '/ServerAlias/{printf "%s ",$2}' $fichier`
    userID=`awk '/AssignUserID/ {printf "%s ",$2}' $fichier`

echo -e "| "$sitename" | "$serverName" | "$serverAlias" | "$userID" | "
# Size DocumentRoot
    home=($(awk -F"DocumentRoot" '/DocumentRoot/{print $2}' $fichier))
    for i in "${home[@]}"
    do
    du -ksh $i && echo -e "|\n"
    done

Edit for @muru :

hey thanks for your answer. I'm really new in shell-scripting just learning it since a couple days.

I need to export values of my virtualhosts in apache2 sites-enabled like ServerName ServerAlias DocumentRoot and so on. From there I run a du ksh on the extracted Document Root to see the size of eacj website hosted. Afterwards the script will run a dig on the extracted Servername & aliases to check where it really points out.

The final format would be ideally set in a "board" to be exploited online on a website that uses a special format for it (each first title rows start with pipe+underscore+dot |_. the last rows end with pipe only then each line after the fist one start and end with a pipe).

However when running the script I can't make the desired format work, if I put the echo -e "| \n" outside of the for ; it seems it stops at the first DocumentRoot found in a virtualhost. If i have a website with multi vhost inside it fails to take them all into account.

I suspected something related to the carriage returns cause the output is really weird for me.

switched from echoto printf. feels better.

Couldn't get the desired output with echo "$(du -ksh $i)". Switched the echowith printfand got the desired output. Can't really explain it but still, works.
