So I'm trying to do some simple directory traversal and run some scripts.
The plan was to pass 2 variables to my code with PID=123 DIRNAME=Lalaland bash magic.sh
The script is
echo "SCRIPT BEGIN"
PPWD=$(pwd)
BRC="/../"
echo $PPWD
echo $BRC
echo ${PPWD}${BRC}
cd ${PPWD}${BRC}
git pull
cd ../Web
nodejs server.js
echo "SCRIPT END"
echo ${PPWD}${BRC} returns /../e/git/Gitorade.
git status does not run.
cd ../Web is also broken somehow.
I get this at the end:
SCRIPT BEGIN
/home/git/Gitorade
/../
/../e/git/Gitorade
: No such file or directorye/git/Gitorade
' is not a git command. See 'git --help'.
Did you mean this?
status
: No such file or directoryeb
SCRIPT END
I understand that I have probably made some terrible syntax errors but I have spent some embarassing time debugging this and I have good knowledge of programming languages but none of shell ones. Is there maybe some good tutorial for this or some cheat sheet because I am hopeless...
EDIT:
I have also tried:
echo "SCRIPT BEGIN"
PPWD=$(pwd)
PPWD=${PPWD%$'\r'}
BRC="/../"
echo $PPWD
echo $BRC
echo "${PPWD} ${BRC}"
echo ${PPWD}${BRC}
echo $PPWD "asd"
echo $PPWD "ASD" $PPWD
echo $PPWD$PPWD
echo $BRC$BRC
echo ${PPWD}${PPWD}
cd ${PPWD}${BRC}
git status
cd ./../Gitorade
which resulted in
SCRIPT BEGIN
/home/git/Gitorade
/../
/..//git/Gitorade
/../e/git/Gitorade
asde/git/Gitorade
ASD /home/git/Gitorade
/home/git/Gitorade
/../
/home/git/Gitorade
