When i issue git push or git pull commands, i get

git pull origin mybranch /usr/local/libexec/git-core/git-sh-setup: line 342: cd: ÅÑÈ: EDC5129I No such file or directory.
line 342 in the script shows:
BROWSE /Z22R01/usr/local/libexec/git-core/git-s Line 0000000342 Col
.test -n "$GIT_DIR" && GIT_DIR=$(cd "$GIT_DIR" && pwd) || {
..echo >&2 "Unable to determine absolute path of git directory"

is there any issue with $GIT_DIR ?

file allocate_sh should be changed for the allocation of demo.txt, and assign an lrecl > 259 (for instance 286), otherwise script to_pds.sh will get an error
SPARKID:/u/sparkid/hello_world/hello_world: >./to_pds.sh
cp: FSUM6260 write error on file "//'SPARKID.DEMO.TXT(README)'": EDC5003I Truncation of a record occurred during an I/O operation.
