I am trying to use a HERE document in a docker script file to generate a text file but must be doing something wrong since I get a warning message that I did not expect:
EOF: line 6: warning: here-document at line 0 delimited by end-of-file (wanted `EOF')
This is the sample script I am testing in my docker file:
RUN bash -c "$(/bin/echo -e "cat << 'EOF' | tee -a /test.txt \ \n<test> \ \n someting here \ \n something else here \ \n</test>")" \ EOF
Can anyone see what is wrong in the above statement?
Thanks.
The second EOF should be before the part ")" \ and not after, because it has to represent the closure of the first one above....
So it should be something like this (I have put /tmp/test.txt as I tested as non root user that cannot write into /)
bash -c "$(/bin/echo -e "cat <<EOF | tee -a /tmp/test.txt \ \n<test> \ \n something here \ \n</test> EOF ")"
I also removed the single apex from the first 'EOF'.
I get:
[g.cecchi@ope46 ~]$ ll /tmp/test.txt ls: cannot access '/tmp/test.txt': No such file or directory
[g.cecchi@ope46 ~]$ bash -c "$(/bin/echo -e "cat <<EOF | tee -a /tmp/test.txt \
\n<test> \ \n something here \ \n</test> EOF ")"
<test> something here </test>
[g.cecchi@ope46 ~]$ cat /tmp/test.txt <test> something here </test> [g.cecchi@ope46 ~]$
