All,
I'm using RHL 7.3, and I've got a couple of very simple shell scripts -
one of which is kicking my butt. I just don't understand what it
is/isn't doing.
Here are the details
====================================
Script that works fine:
dokimos_web:logs>more combQV.sh
cp qvcatering_access.log qvcatering_access.log.bak
for i in `ls -rt qvcatering_access_log.2*.log`; do cat $i >>
qvcatering_access.log; done
mv qvcatering_access_log.2*.log saved
===========================================
Script (computeStats.sh) that doesn't work and it's output (Version 1):
# set environment variables
./home/dokimos_web/.bash_profile
# TC defined in .bash_profile file
echo $TC
exit 0
-- ---- ---- ---- ---- ---- ------
results:
dokimos_web:logs>./computeStats.sh
: No such file or directoryokimos_web/.bash_profile
'/computeStats.sh: exit: bad non-numeric arg `0
dokimos_web:logs>
[note: the apparent truncation/overwriting in the "No such file or
directoryokimos_web" line is not a typo on my part - that's the actual
output]
=================================================
Script (computeStats.sh) that doesn't work and it's output (Version 2):
#!/bin/bash
# set environment variables
./home/dokimos_web/.bash_profile
echo $TC
exit 0
-- ---- ---- ---- ---- ---- --
results:
dokimos_web:logs>./computeStats.sh
bash: ./computeStats.sh: bad interpreter: No such file or directory
dokimos_web:logs>
===========================================
I've checked, and bash is in /bin.
So.... I have a couple of questions:
1. why isn't the #!/bin/bash line required in the script that works?
2. why doesn't the other script work? [note that computeStats.sh has
executable permissions for all users]
Thanks,
Scott
