hi all,
sorry for replaying on this thread again.
but i came across this problem again,
to summarize , binary line of "^@" gets inserted into a file whenever i try to truncate it by > /filename. This has happened to files which had no other script/service writing to it.
though i tried to truncate the files by echo /dev/null > /filename, and am keeping my fingers crossed this time.
any insight into this rouge behaviour will be appreciated.
thanks in anticipation
cheers

sed 's|^xyz.abc *= *.*|xyz.abc=60|' /test/myFile.properties > /test/myFile.properties1
myFile.properties has the last line as xyz.abc=23 does not end with newline.
When I run this command the last line is truncated if there is no newline character at EOF. Looking for an alternative here. (1 Reply)
