Bug comparing timestamp of a file with its touched version
Hi,
I'm new to unix,I wanna know how can I compare timestamp of a file with its touched version.i.e I want to be sure if the touch command has worked properly i.e if the file has been touched then a msg should be printed saying success else failure.All this to be incurred in a script.
Any suggestions are welcome.

Thanks in advance

If the stat(1) utility is available, then here is an example of one way of doing it
Code:
#!/bin/bash

FILE=./testfile        # replace with your file
stat1=$(stat --printf="%Z" $FILE)
touch $FILE
stat2=$(stat --printf="%Z" $FILE)
if [[ $stat1 = $stat2 ]]
then
   echo "touch failed"
else
   echo "touch succeeded"
fi

Thanks in advance
if you wanna check for the sucess or failuer of some command
check for $? after that command
e.g
Code:
 
touch filename
if [ $? -eq 0 ];then
echo "done"
else
echo "not done"
fi
