If you need to process items in some non-trivial way you can take advantage of the scripting interface the application provides. This is accessible on command line as copyq eval SCRIPT or copyq -e SCRIPT where SCRIPT is string containing commands written in Javascript-similar scripting language (Qt Script with is ECMAScript scripting language).

Every command line option is available as function in the scripting interface. Command copyq help tab can be written as copyq eval 'print(help("tab"))' (note: print is needed to print the return value of help("tab") function call).

Searching Items

You can print each item with copyq read N where N is item number from 0 to copyq size (i.e. number of items in the first tab) and put item to clipboard with copyq select N. With these commands it’s possible to search items and copy the right one with a script. E.g. having file script.js containing

var match = "MATCH-THIS";
var i = 0;
while (i < size() && str(read(i)).indexOf(match) === -1)

and passing it to CopyQ using cat script.js | copyq eval - will put first item containing “MATCH-THIS” string to clipboard.

Working with Tabs

By default commands and functions work with items in the first tab. Calling read(0, 1, 2) will read first three items from the first tab. To access items in other tab you need to switch the current tab with tab("TAB_NAME") (or copyq tab TAB_NAME on command line) where TAB_NAME is name of the tab.

For example to search for an item as in the previous script but in all tabs you’ll have to run:

var match = "MATCH-THIS";
var tabs = tab();
for (var i in tabs) {
    var j = 0;
    while (j < size() && str(read(j)).indexOf(match) === -1)
    if (j < size())
        print("Match in tab \"" + tabs[i] + "\" item number " + j + ".\n");

Scripting Functions

As mentioned above, all command line options are also available for scripting e.g.: show(), hide(), toggle(), copy(), paste().

Reference for available scripting functions can be found at Scripting API.

Other supported functions can be found at ECMAScript Reference.
