I came up with this command
pub global list -v 2>/dev/null | awk '{split($0, a," "); printf \
"pub global activate "; if(a[8]=="") printf a[3]; else printf \
"-sgit " a[8]; print "" }' | xargs -0 bash -c
to update all my globally activated packages.
pub global list -v
outputs
FINE: Pub 1.9.0-edge.43835
MSG : dart_style 0.1.3
MSG : den 0.1.5
MSG : linter 0.0.1 from Git repository "[email protected]:dart-lang/linter.git"
MSG : polymer 0.15.5+1
MSG : stagehand 0.1.5+4
MSG : test_runner 0.2.16
The above command generates these commands from the output
pub global activate dart_style
...
pub global activate -sgit "[email protected]:dart-lang/linter.git"
...
That's quite complicated. Is there an easier way?
Well, you don't need to apply a split in the awk.
Another improve , get rid of the if contional and use the ternary operator (as Etan explain in the comments):
awk '{var=$8==""?$3:"-sgit "$8;print "pub global activate "var }'
The final stuff should be something close to:
pub global list -v 2>/dev/null |\
awk '{var= $8==""? $3: "-sgit " $8
print "pub global activate "var }'| bash -s
Alternatively a system call can be done inside the awk code:
pub global list -v 2>/dev/null |\
awk '{var=$8=="" ? $3: "-sgit " $8
cmd="pub global activate "var
system(cmd)
close(cmd)}'
