\n In the category “little gems that make my life better”<\/em> (which in fact is synonym for “Why
\n everyone would be better off with the Z-Shell”<\/em>), today I’m reading from my .zshrc file. Zsh has
\n those fine pre- and post-exec hooks. Those let you specify functions that are run before a command
\n is executed, and right after. I’m using a tabbed konsole all of the time, with some DCOP magic,
\n it’s easy to monitor your commands from another tab.
\n But let the .zshrc script speak:<\/p>\n

\n# Define colors\nBLACK=\"%{\"$'\\033[01;30m'\"%}\"\nGREEN=\"%{\"$'\\033[01;32m'\"%}\"\nRED=\"%{\"$'\\033[01;31m'\"%}\"\nYELLOW=\"%{\"$'\\033[01;33m'\"%}\"\nBLUE=\"%{\"$'\\033[01;34m'\"%}\"\nBOLD=\"%{\"$'\\033[01;39m'\"%}\"\nNORM=\"%{\"$'\\033[00m'\"%}\"\n\nif [ \"$KONSOLE_DCOP_SESSION\" ]\nthen\n        if [ `\/usr\/bin\/whoami` != 'root' ]\n                then\n                alias ssh='konsolewrap  ssh'\n                alias lftp='konsolewrap  lftp'\n                alias sftp='konsolewrap  sftp'\n                alias ssh='konsolewrap  ssh'\n                alias su='konsolewrap su'\n                alias ipy='konsolewrap ipython'\n        preexec () {konsole-rename-cmd $1}\n        precmd () {\n            konsole-rename-path\n            if [ `\/bin\/hostname` = 'luna' ]; then\n                RPROMPT=\"${BLUE}[${YELLOW}%*${NORM} `battery`${BLUE}]${NORM}\"\n            fi\n        }\n        fi\nfi\n    <\/pre>\n
    This involves two small scripts, konsole-rename-path and konsole-rename-cmd. Those basically
\n    change the name of the tab with a dcop call. konsole-rename-path looks like this:<\/p>\n
\n#!\/bin\/bash\n# This small script renames the konsole tab to the current working directory\n\nif [ \"$KONSOLE_DCOP_SESSION\" ]\nthen\n    dcop `echo ${KONSOLE_DCOP_SESSION}` renameSession \"`echo $PWD | sed s,^$HOME,~,`\"\nfi\n    <\/pre>\n
    This is konsole-rename-cmd:<\/p>\n
\n#!\/bin\/bash\n# This small script renames the konsole tab to the current command\n\nif [ \"$KONSOLE_DCOP_SESSION\" ]\nthen\n    dcop `echo ${KONSOLE_DCOP_SESSION}` renameSession \"$1\"\nfi\n    <\/pre>\n
    konsolewrap is for commands like ssh, tabs get the hostname in this case:<\/p>\n
\n#!\/bin\/sh\ndcop $KONSOLE_DCOP_SESSION renameSession \"$*\"\nexec $cmd \"$@\"\n    <\/pre>\n
    This can of course all be neatified, but it does the job pretty well. I can start a job in
\n    one tab, switch to another, and I see the tabname change when the command is finished. This
\n    is somewhat similar to the “Monitor for Silence \/ Activity” in konsole, but a bit more
\n    flexible.<\/p>\n
\n    As you see, there’s also a variable set, RPROMPT. This produces a clock and the current
\n    battery charge state. In colors and all.<\/p>\n
\nbattery(){\n        CBS=`acpi | awk '{print $4}' | awk -F % '{print $1}'`\n        if [[ ${CBS} -lt 35 ]] && [[ ${CBS} -gt 10 ]]; then\n                echo \"${YELLOW}${CBS}%%${NORM}\"\n        elif [[ ${CBS} -lt 10 ]] || [[ ${CBS} -eq 10 ]]; then\n                echo \"${RED}${CBS}%%${NORM}\"\n        else\n                echo \"${GREEN}${CBS}%%${NORM}\"\n        fi\n}\n    <\/pre>\n
    Low battery value, and the right hand side prompt’s battery percentage goes yellow, then red.<\/p>\n
\n    KDE4’s konsole has a very similar feature built in, so less fiddling with scripts in the
\n    future. :-)<\/p>\n","protected":false},"excerpt":{"rendered":"
