[SOLVED] bash script: to truncate filename

casualzone · 04-21-2011, 11:51 PM

try to write a simple bash script

If the input $1 is a "myfilename.txt",
How could I store the "myfilename" as my another variable instead of "myfilename.txt". I want the script to make a new directory name as myfilename

I believe there is bash(1)-fu to solve this sort of thing, but I'm pretty fond of g/awk(1):

Code:

_name=$(echo ${1} | awk -F'.' '{print $1}')

Here is a pure bash solution:

Code:

dir_name=${1%.*}

If your name has several dots in it like
my.file.name.txt

then it will only delete the last part like
my.file.name

If you want the output to be just
my

then you can use

Code:

dir_name=${1%%.*}

How about for the csh case?
