Trying to test for both upper and lower case directories
I am trying to get a script to print out whether a directory is lowercase uppercase or both. This is what I've got so far:
Code:
echo -e read "enter name"
read server
for DIR in $(find /tmp/$server -type d -prune | sed 's/\.\///g');do if expr match "$server" "[a-zA-Z]*$" > /dev/null; then echo "$server - Both"; elif expr match "$server" "[[:upper:]]*$"; then echo "$server - Uppercase"; elif expr match "$server" "[[:lower:]]*$" > /dev/null; then echo "$server -there are lower";fi;done
Now this will let me know whether either an upper or lowercase directory is present for the servername and also if both are present, like this
/tmp/server -lowercase present
/tmp/SERVER - uppercase present.
if both are present, it prints both
However, if I type in a lowercase name and there is only a lowercase directory, it still prints "both." What am I doing wrong? I think "[a-zA-Z]* is bad because it matches incorrectly. I think I need something like "[[:upper:]]*$ && [[lower:]]" but this does not work.
Any help would be greatly appreciated!

# cat test_cases.sh
#!/bin/bash
for DIR in $( find . -type d | sed 's/\.\///g' )
do
if expr match "$DIR" "[[:lower:]]*$" > /dev/null
then
echo "$DIR - Lowercase"
elif expr match "$DIR" "[[:upper:]]*$" > /dev/null
then
echo "$DIR - Uppercase"
elif expr match "$DIR" "[0-9]*$" > /dev/null
then
echo "$DIR - Numeric"
elif expr match "$DIR" "[a-zA-Z]*$" > /dev/null
then
echo "$DIR - Mixed"
elif expr match "$DIR" "[a-zA-Z0-9]*$" > /dev/null
then
echo "$DIR - Alphanumeric"
fi
done
find . -type d | sed 's/[^a-zA-Z]//g' | while read DIR
do
case "$DIR" in
*[a-z][A-Z]*|*[A-Z][a-z]*) echo "$DIR Mixed" ;;
*[A-Z]*) echo "$DIR Uppercase" ;;
*[a-z]*) echo "$DIR Lowercase" ;;
esac
done
I think why what I have is not working is because the input that the user enters will only be uppercase or lowercase not both. So when my script checks the directories, it says yes there is uppercase when you enter the uppercase input and yes there is lowercase when you enter the lowercase input.
But then since the user does not enter both upper and lowercase input, the script will never say both. Is there an easy way to get the script to convert the input into uppercase while also checking for the lowercase name? Or am I off track here? Any help is appreciated. Also, thanks for your previous responses.
This script is what I have. It does identify both lower and upper case but will never print "both." For example, if I enter david as the input it responds david -lowercase. If I enter DAVID as the input it responds DAVID- uppercase. But if I type either david or DAVID it never prints both. But in reality there are both DAVID and david directories in /tmp such as this:
/tmp/david
/tmp/DAVID
I realize this may be a dumb question on my part, but it appears to me that the reason this script does not return the "both" value is that I am entering only lowercase or uppercase into the input and it is being read as such and not looking to see if there are the two directories.
Code:
echo -e read "enter name"
read netapp
for DIR in $(find /usr/openv/netbackup/db/images/$netapp -type d -prune | sed 's/\.\///g');do if expr match "$netapp" "[a-zA-Z]*$" > /dev/null; then echo "$netapp - Both"; elif expr match "$netapp" "[[:upper:]]*$"; then echo "$netapp - Uppercase"; elif expr match "$netapp" "[[:lower:]]*$" > /dev/null; then echo "$netapp -there are lower";fi;done
Thanks again for your patience with my newbie questions!

You do realize you don't have to jam it all on one line? You can put a newline wherever you have a ; and immediately after pipes too.
Code:
echo -e read "enter name"
read netapp
for DIR in $(find /usr/openv/netbackup/db/images/$netapp -type d -prune |
sed 's/\.\///g')
do
if expr match "$netapp" "[a-zA-Z]*$" > /dev/null
then
echo "$netapp - Both"
elif expr match "$netapp" "[[:upper:]]*$"
then
echo "$netapp - Uppercase"
elif expr match "$netapp" "[[:lower:]]*$" > /dev/null
then
echo "$netapp -there are lower"
fi
done
I suggest trying my code from earlier, with some slight changes now that it's clearer what you want:
Code:
find /usr/openv/netbackup/db/images/$netapp -type d -prune | while read DIR
do
# convert /path/to/abc9DEF into abcDEF
NAME=$(basename "$DIR" | sed 's/[^a-zA-Z]//g')
case "$NAME" in
*[a-z][A-Z]*|*[A-Z][a-z]*) echo "$DIR Mixed" ;;
*[A-Z]*) echo "$DIR Uppercase" ;;
*[a-z]*) echo "$DIR Lowercase" ;;
esac
done
How it works: Take a name like 'abc9DEF' and strip all non A-Z from it, so you get abcDEF.
Then check for an uppercase letter followed by a lowercase one, or vice versa. If you find that, it's mixed case. Otherwise, it's either all-upper or all-lower.
