[RESOLVED] [Pre-/Post-build steps] Pipe redirection

[smalcom]

I'm trying to use pipe redirection in pre-build script

Code Select Expand

grep -r avr_kind_t $(PROJECT_DIR)simavr/cores/ | awk -F '[ :]' '{print $1 "=" $3;}'
and got error:

-------------- Build: Config in simavr (compiler: GNU GCC Compiler)---------------

Running target pre-build steps
grep -r avr_kind_t ...path.../simavr/cores/ | awk -F '[ :]' '{print  "=" ;}'
Usage: awk [POSIX or GNU style options] -f progfile [--] file ...
....

Good, i added '$':

Code Select Expand

grep -r avr_kind_t $(PROJECT_DIR)simavr/cores/ | awk -F '[ :]' '{print $$1 "=" $$3;}'

And got:

-------------- Build: Config in simavr (compiler: GNU GCC Compiler)---------------

Running target pre-build steps
grep -r avr_kind_t ...path.../simavr/cores/ | awk -F '[ :]' '{print $1 "=" $3;}'
Usage: awk [POSIX or GNU style options] -f progfile [--] file ...
...

I selecting last command from output:

Code Select Expand

grep -r avr_kind_t ...path.../simavr/cores/ | awk -F '[ :]' '{print $1 "=" $3;}'
paste it to console and got result without error:

user@host ...path.../simavr/simavr $ grep -r avr_kind_t ...path.../simavr/cores/ | awk -F '[ :]' '{print $1 "=" $3;}'
...path.../simavr/cores/sim_mega48.c=mega48
....

What i'm doing wrong?
Thanks.

Problem resolved: internal single quotes

' must be changed with

'\''
Result:

Code Select Expand

bash -c 'grep -r avr_kind_t cores/ | awk -F '\''[ :]'\'' '\''{print $1 "=" $3;}'\'''
