Not so long ago I began to learn all the delights of programming in bash. I write scripts to automate routine actions that occur in the course of work (C programmer under Nix). It seems to be =) So, it became necessary to use bash clipboard (using only bash tools and standard Solaris utilities). Those. copy the value of a variable to this very buffer. "Xsel" and "xclip" no. The specificity is such that all work takes place on a remote customer’s wheelbarrow, in the grid of which there is even no Internet. Accordingly, I can not put any software. Tell me how to do it (if this is at all possible)? Googling did not produce results.
PS I hope the live broadcast at least someone reads.
