Zsh: slow when run bash shell script












0














I have a script that written completely with bash compatible in mind, that used with dmenu to handle a task.



I use zsh as default shell, in that script I have shebang like #!/usr/bin/env bash, dmenu invoke the script to do task pretty fast, but when I change interpreter to use origin zsh like below:



#!/usr/bin/env zsh

emulate -L zsh


comparing visual when surf through task in dmenu, I can see visual delay when use zsh as interpreter than bash. This struck me because I'm trying to migrate completely from bash/sh to zsh (zsh supports better for writing shell scripts imho)






shell-script command-line zsh dmenu

          4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
