Right now you're telling it to check if the word 'disconnecting' exists in the files = and 0. Comparisons between strings have to happen between [ ].

Code:
if egrep -q -s "/usr2/bin/ftpd" /var/tmp/check.tmp ||
        [ $(tail -20 /usr2/logs/ftp.log | grep -q disconnecting) = 0 ]
then
...
fi

i want to check for the output of grep -c

so when i run

Code:
tail -20 /usr2/logs/ftp.log | grep -c disconnecting

it gives me a count in the output, so if the count is equal to 0 then i want to echo ftp is running.

ftpd_selinux(8) 					 ftpd SELinux policy documentation					   ftpd_selinux(8)

NAME
ftpd_selinux - Security-Enhanced Linux policy for ftp daemons. DESCRIPTION
Security-Enhanced Linux provides security for ftp daemons via flexible mandatory access control. FILE_CONTEXTS SELinux requires files to have a file type. File types may be specified with semanage and are restored with restorecon. Policy governs the access that daemons have to files. Allow ftp servers to read the /var/ftp directory by adding the public_content_t file type to the directory and by restoring the file type. semanage fcontext -a -t public_content_t "/var/ftp(/.*)?" restorecon -F -R -v /var/ftp Allow ftp servers to read and write /var/tmp/incoming by adding the public_content_rw_t type to the directory and by restoring the file type. This also requires the allow_ftpd_anon_write boolean to be set. semanage fcontext -a -t public_content_rw_t "/var/ftp/incoming(/.*)?" restorecon -F -R -v /var/ftp/incoming BOOLEANS
SELinux policy is based on least privilege required and may also be customizable by setting a boolean with setsebool. Allow ftp servers to read and write files with the public_content_rw_t file type. setsebool -P allow_ftpd_anon_write on Allow ftp servers to read or write files in the user home directories. setsebool -P ftp_home_dir on Allow ftp servers to read or write all files on the system. setsebool -P allow_ftpd_full_access on Allow ftp servers to use cifs for public file transfer services. setsebool -P allow_ftpd_use_cifs on Allow ftp servers to use nfs for public file transfer services. setsebool -P allow_ftpd_use_nfs on system-config-selinux is a GUI tool available to customize SELinux policy settings.
