I have a bash script on a Solaris server to provide an alert if a file is in a folder location for longer than 5 minutes.

if [ -f $1 ]

However, it is throwing a lot of false positives so I need to know how to add an additional filter when looking for a file to anything which was modified / created longer than 5 minutes ago.

If a file in x folder location is older than 5 minutes, I would like the script to report that.

This question is not the same as the "possible duplicate" as I am requesting assistance with Solaris Linux and that ticket is referencing MAC and Linux, the commands mentioned there are not working in my Solaris box!

  • @Panki I am using Solaris which seems to have a different command set - that's why it is not the same as that ticket, thank you for linking though, interesting stuff

  • Are you using Solaris 11, or 10? (or 9 or 8?!?)

You can work around it by manually creating a temporary file that's dated to five minutes ago, then ask find for files that are not newer than your temporary file:

if [ "$?" -ne 0 ]
  echo "Error creating temporary file; exiting"
  exit 1
touch -t $(( $(date  +%Y%m%d%H%M) - 5 )) "$tempfile"
find /your/path -type f ! -newer "$tempfile"
rm "$tempfile"

Find all files in /foo which are older than 5minutes

find /foo -type f  -mmin +5 
  • responds with : find: bad option -mmin

  • @Thomas_ If the default Solaris find doesn't support -mmin, maybe you can install GNU find? (opencsw.org/packages/findutils)

  • @Thomas_ Are you using /usr/bin/find by default? Try /usr/xpg4/bin/find instead.

    newer Solaris do have -mmin in the xpg4 version; Solaris 10: no; Solaris 11: yes
