ezz is the edit helper program for the generic zz clip board program.
The clip board is \$ZZ (default: \$HOME/.zz). Options and modes are:
"ezz" edit \$ZZ
"... | ezz" write STDIN from pipe to \$ZZ and call editor
"... | ezz +" add STDIN from pipe to \$ZZ and call editor
"ezz 'perl-script'" run perl-script on \$ZZ
"ezz - 'perl-script'" run perl-script on \$ZZ and write result to STDOUT
"ezz filter [args]" run filter [with args] on \$ZZ
"ezz - filter [args]" run filter [with args] on \$ZZ and write result to STDOUT
"ezz -r" restore \$ZZ from last ezz operation (\$ZZ~)
Examples:
ls -l | ezz
ezz "s/ /_/g"
ezz head -3
ezz - head -3
Limitation: zz does not work across different accounts!
