Fetch PID
Hi All,

i get this output when i do PS UX

Code:
tdntp  9263  0.0  0.0  98464  3200 pts/1    S+   14:16   0:00 vim FAB1_600015_CONRAD.A0_7XYZ12345.000_LT-SWET.01_LTPA25L_

I want to get the PID of certain specefic filename.

so i tried

Code:
ps ux | pgrep FAB1_600015_CONRAD.A0_7XYZ12345.000_LT-SWET.01_LTPA25L_

But still i get no PID as the command is preceded by "vim".....is there any way out to get PID of only Filename.

Hi Buddy,

I am writing a script to FTP out files from server 1 to server 2.These files are generated by another Java application running in server 1.

Before FTP out these files i want to check if these files are complete or it is still been access by any other process (Could be move or copy by java application).

So i thought of doing PS UX | pgrep Filename

But this always returns null as the output from PS UX will be

Code:
mv FAB1_600015_CONRAD.A0_7XYZ12345.000_LT-SWET.01_LTPA25L_
 or
cp FAB1_600015_CONRAD.A0_7XYZ12345.000_LT-SWET.01_LTPA25L_

So i want to just check grep for FAB1_600015_CONRAD.A0_7XYZ12345.000_LT-SWET.01_LTPA25L_ by not considering the command it is used with.

you can simply check like below

Code:
 
ps -ef | grep -v grep | grep "FAB1_600015_CONRAD.A0_7XYZ12345.000_LT-SWET.01_LTPA25L_"
[ "$?" -eq "0" ] && echo "Safe to FTP" || echo "Some commands accessing the file"

Use fuser or lsof commands to check if the file is open by another program

Hi Buddy,

I have tried using smething like

Code:
if [ -f "$Filename" -a "$( fuser "$filename}" 2>/dev/null )" = "" ]
then 
echo "File is closed"
else
echo "file is open"

But i found this command always gives File is closed even when i open the file with "vi"....So i thought of going for other option like PS UX....

Any suggestions?

Is it typo ?

"$( fuser "$filename}" 2>/dev/null )" = ""
