Command not found when invoking a function

[dspinellis]

[dds@stereo dgsh]$ example/5x5.sh
bash: f: command not found
[dds@stereo dgsh]$ cat example/5x5.sh
#!/usr/bin/env dgsh

f()
{
  echo hi
}

call f | paste

[mfragkoulis]

f should be exported:

export -f f

[dspinellis]

Thanks! Can we make this implicit when there is a call statement?

[dspinellis]

Also, the following example also fails.

#!/usr/bin/env dgsh

f()
{
  echo hi | paste
}

export -f f
call f
[dds@stereo dgsh]$ example/5x5.sh
bash: --dgsh-negotiate: invalid option

The following also fails with the above message

#!/usr/bin/env dgsh

row()
{
  dgsh -c --dgsh-negotiate 'echo hi | paste'
}

export -f row
call row

[mfragkoulis]

The following works:

#!/usr/bin/env dgsh

row()
{
  dgsh -c 'echo hi | paste'
}

export -f row
call row | cat

Why it works:

• call stands for bash --dgsh-negotiate, which implies it is part of a dgsh pipeline
• the dgsh command within the function is standalone and therefore it should not negotiate

[dspinellis]

Indeed it works. But we must make it more intuitive.
