This is for bash shell.
Yes, I tried below:
cat test.txt |awk '{print substr($1, 1, length-1)}'
This will allow me to remove whatever last character in the line, but the requirement is only remove if numeric (1-9).
Appreciate if any suggestion given.
Thanks
You still haven't told us what operating system you're using.
Note that numeric is 0 through 9; not 1 through 9.
Note that awk and sed are perfectly capable of reading a file by itself without creating a pipe and an unneeded process (cat) to slow down processing and waste system resources.
One might try any of the following (all of which are very similar to suggestions in the threads listed at the bottom of this page) each of which should do what you requested:
If you're trying this on a Solaris/SunOS system, change awk in either of the above to /usr/xpg4/bin/awk or nawk.
