Hi everybody! :slight_smile: :smiley: :smiley: :slight_smile:

it's great to be here since this is my first post.

touch /base/oracle/FRA/XMUT00/RMAN_FLAG
touch /base/oracle/FRA/XRLL00/RMAN_FLAG

find directory name containing RMAN_FLAG :

$ find /base/oracle/FRA -name RMAN_FLAG -print|xargs -n1 dirname |sort -u
/base/oracle/FRA/XMUT00
/base/oracle/FRA/XRLL00

find all file named *.arc :

$ find /base/oracle/FRA -name "*.arc" -print
/base/oracle/FRA/XARS00/XARS00arch6563.arc
/base/oracle/FRA/XARS00/XARS00arch6562.arc
/base/oracle/FRA/XARS00/XARS00arch6559.arc
/base/oracle/FRA/XARS00/XARS00arch6560.arc
/base/oracle/FRA/XARS00/XARS00arch6561.arc
/base/oracle/FRA/XBIO00/XBIO00arch286.arc
/base/oracle/FRA/XMUT00/XMUT00arch3624.arc
/base/oracle/FRA/XMUT00/XMUT00arch3616.arc
/base/oracle/FRA/XMUT00/XMUT00arch3613.arc
/base/oracle/FRA/XMUT00/XMUT00arch3621.arc
/base/oracle/FRA/XMUT00/XMUT00arch3626.arc
/base/oracle/FRA/XRLL00/XRLL00arch5199.arc
/base/oracle/FRA/XRLL00/XRLL00arch5200.arc
/base/oracle/FRA/XRLL00/XRLL00arch5201.arc
/base/oracle/FRA/XRLL00/XRLL00arch5202.arc

I want to remove all *.arc files execpt those found in directories where RMAN_FLAG is present

I tried :

EXCLU=$(find /base/oracle/FRA -name RMAN_FLAG -print|xargs -n1 dirname |sort -u)

for file in $(find /base/oracle/FRA -name "*.arc" -print|grep -v ${EXCLU})
do
rm $file
done

but grep does not work with multiple values (I know perl grep function accept a list of values but shell grep don't :mad: )

any hints? using sed and/or maybe awk?

I'm on HPUX standard grep/awk/sed (not gnu)

thanks

This works for me:

#!/bin/ksh

for f in $( find /base/oracle/FRA -name *.arc -print )
do
  if [ ! -f "$( echo $f | sed 's/\/[^\/]*$/\/RMAN_FLAG/' )" ]; then
    rm -f $f
  fi
done

I've tested it with ksh, maybe some small modifications are needed for other shells.

find /base/oracle/FRA -name RMAN_FLAG -print|xargs -n1 dirname |sort -u > tmp
for file in $(find /base/oracle/FRA -name "*.arc" -print|grep -v -f tmp)
Do the above modification to make grep work
