Changing PWD in a script to allow for accessing file without prefixing full path
I know I should be able to change the current working directory of a bash script by doing something akin to
cd `dirname $MYPATH`
but for some reason this doesn't work (or not as I imagined it).
#!/bin/bash
WAYPATH="/home/user/articles"
TEST_PATH="/home/user/testing"
# Set working directory of the script to be testing
cd `dirname $TEST_PATH`
for i in $(ls $WAYPATH); do
another_command $i $i.r > $TEST_PATH/htmls/$i.html
done
My goal here is to allow the bash script to find the files located in TEST_PATH (which have matching name to those in WAY_PATH) without having to prefix them with the full path (because another_command) makes use of the whole argument passed to it.
So this is a lesson on understanding what commands do after reading about them on Stackexchange. I was using
cd `dirname $MYPATH`
following this answer where they achieved the desired result
cd `dirname $0`
$0 is the full path of the bash script, so dirname is required to return the path without the name of the file.
Instead, for an arbitrary supplied path is sufficient to do a simple
cd $MYPATH
as suggested in comments.
