-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear list-members,
last week I've updated my workstation cluster client (amd 64 bit) from SuSE 10.0 to openSUSE 10.3. My bash-version is 3.2.25(1)-release. Now I've problems with a bash script, which I used (with bash 3.1) for years without any problems. I really don't understand what's going on. I've reduced my original script to a minimal script which reproduces the output redirection error. The script works as follows: My first script (local.sh) reads a list of worksation cluster clients from hosts.inp in a loop and prints some output to output.txt. In the loop a second script (remote.sh) is called in a ssh instruction. remote.sh then writes some output to the same output.txt file, but this output doesn't reach the output file correctly. Both the bash-scripts and the output file are stored on an NFS-Filesystem (on the workstation cluster server), so every client can access them. | less hosts.inp client1 client2 client3 client4 | less local.sh #!/bin/bash OUTPUT=$HOME/bashtest/output.txt INPUT_HOSTS=$HOME/bashtest/hosts.inp REMOTE_SKRIPT=$HOME/bashtest/remote.sh echo "created from $HOME/bashtest/local.sh" > $OUTPUT for HOST in `cat $INPUT_HOSTS` do ~ echo $HOST >> $OUTPUT ~ ssh $HOST $REMOTE_SKRIPT ~ echo "" >> $OUTPUT done | less remote.sh #!/bin/bash OUTPUT=$HOME/bashtest/output.txt echo "TEST2" >> $OUTPUT | less output.txt created from /home/user1/bashtest/local.sh client1 [EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@ client2 [EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@ client3 [EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@ client4 [EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@ Instead of all the [EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@ rows, output.txt should contain the text TEST2 less thinks output.txt were a binary file. I don't understand, why the output-redirection in remote.sh doesn't work. If I do the output-redirection in remote.sh to another file, for example OUTPUT2=$HOME/bashtest/output2.txt echo "TEST2" >> $OUTPUT2 then it works. The output-redirection only fails, when the redirection is to the same file which is also be written from local.sh. I appreciate receiving any help. best regards, Verena Alishahi - -- Verena Alishahi Institut für Chemie und Dynamik der Geosphäre ICG-1: Stratosphäre Tel.: +49 2461 61-6221 E-Mail: [EMAIL PROTECTED] - -------------------------------------------------------------------------- - -------------------------------------------------------------------------- Forschungszentrum Jülich GmbH 52425 Jülich Sitz der Gesellschaft: Jülich Eingetragen im Handelsregister des Amtsgerichts Düren Nr.
