script to run shell command and insert results to existing xml file
Hi. Thanks for any help with this. I'm not new to programming but I am new to shell programming. I need a script that will
1. execute 'df -k' and return the volume names with specific text 2. surround each line of the above results in opening and closing xml tags 3. insert the results of step #2 into an existing file after a specific opening xml tag. Any help would be greatly appreciated! littlejon  |

I have this old script ksh script which takes the output from df and produces a html page. It is specific to HP-UX (hence the "df -Pkl") but you could adapt it to your needs. You probably don't need the bar graph showing disk capacity! Code:
#!/usr/bin/ksh exec 3> df.html print -u3 '<HTML><HEAD><TITLE>STATS</TITLE></HEAD><BODY>' print -u3 '<H3>'$(uname -n)'</H3><TABLE BORDER=2 CELLSPACING=0 CELLPADDING=2>' print -u3 '<TR><TH>Filesystem</TH><TH>1024-blocks</TH><TH>Used</TH>' print -u3 '<TH>Available</TH><TH>Capacity</TH><TH>Mounted On</TH></TR>' df -Pkl |awk 'NR>1 && NF==6'|sort|while read FS SIZE USED FREE PERC MOUNT do print -u3 '<TR><TD>'$FS'</TD><TD ALIGN=RIGHT>'$SIZE'</TD>' print -u3 '<TD ALIGN=RIGHT>'$USED'</TD><TD ALIGN=RIGHT>'$FREE'</TD>' print -u3 '<TD><TABLE BORDER=0 CELLSPACING=1 CELLPADDING=0><TR>' print -u3 '<TD WIDTH='$((150*$USED/$SIZE))' BGCOLOR="black"></TD>' print -u3 '<TD WIDTH='$((150*$FREE/$SIZE))' BGCOLOR="gray"></TD>' print -u3 '<TD><FONT SIZE=-1 COLOR=black> '$PERC'</FONT></TD>' print -u3 '<TR></TABLE></TD><TD>'$MOUNT'</TD></TR>' done print -u3 '</TABLE><P>Generated at '$(date '+%H:%M on %d-%b-%y')'</BODY></HTML>' exec 3<&- |

You can try something like that : Code:
result_file=df.dat
open_tag='<TAG>'
close_tag='</TAG>'
insert_point='<XML>'
df_file=/tmp/$$.tmp
temp_file=/tmp/$$.tmp
# Build lines to be inserted in result file
df -k | tail +2 | while read line
do
echo "${open_tag}\n${line}\n${close_tag}"
done >> ${df_file}
# Insert lines in result file
sed -e "/${insert_point}/r ${df_file}" ${result_file} > ${temp_file}
mv ${temp_file} ${result_file}

Thanks to both Ygor and Aigles. I went with Aigles' suggestion and it worked like a charm. Of course, I tweaked it to meet my needs. I was originally trying to use standard programming techniques to solve this problem. I am now officialy amazed at the power of sed and shell programming. Thank you, again! And, thanks to unix.com for the forum!
