This simple procedure takes 3 arguments as the parameters: Text Foreground color Background color It prints the text to the terminal in selected colors. function print_color { local text=$1 local fg=$2 local bg=$3 case "$fg" in red) fg="31m" ;; green) fg="32m" ;; yellow) fg="33m" ;; blue) fg="34m" ;; white) fg="37m" ;; black) fg="30m" ;; *) [...] It’s very simple to rename the files to lowercase/uppercase using awk: Lowercase ls -1rt | awk ‘{ printf("mv %s %s\n", $0, tolower($0)) | "sh" } END { close("sh") }’ Uppercase ls -1rt | awk ‘{ printf("mv %s %s\n", $0, toupper($0)) | "sh" } END { close("sh") }’ print -n "Enter Your password:" stty_orig=`stty -g` trap "stty ${stty_orig}; exit" 1 2 3 15 stty -echo >&- 2>&- read PASS stty ${stty_orig} >&- 2>&- trap 1 2 3 15 print trap :catches interruptions. I.e. if the user presses Ctrl+C, the normal stty mode is set before stopping the program stty -echo :switches off the [...] It’s not possible to get the value of the loop variables in some versions of ksh. Example: #!/bin/ksh num=0 cat $0 | while read line ; do let num=num+1 done echo "Number=$num" This script will return “Number=0″ as the result on some Linux machines. Here is the workaround for the problem: You should change the [...] ls -1 | cpio -o | cpio -ivt | awk ‘{print $NF, $(NF-1), $(NF-4), $(NF-3) }’ Warning: I/O expensive for the large files! Perl: @a = localtime((stat($my_file))[9]); $a[4]++; printf "%02d%02d%02d",@a[5,4,3]; If the whole output of the complex script should be redirected to the log, the following trick could be used. if [ "$1" != "-log" ] ; then $0 -log "$@" 2>&1 | tee the_log_file.$$.log Here is very simple trick to force the grep command to display file name, when it’s used together with find operation. Just write /dev/null as the “second file” find . -type f -exec grep somestring {} /dev/null \; Here is the small reminder about the syntax of the “case” command and the usage of the pattern lists. #!/bin/ksh print -n "Please enter the line: " read line case "$line" in ?(dog|cat) ) print "zero or one occurrence of any pattern" ;; *(low|high) ) print "zero or more occurrences of any pattern" ;; @(duncan|methos) [...] echo $PATH| awk -v RS=":" ‘{ print $0 }’ echo $LD_LIBRARY_PATH |awk -v RS=":" ‘{ system ( "ls -rltd " $0 ) }’ Warning! As far as the option ‘-v’ is used, the new awk(nawk in some systems) should be used. To check if the new version of awk is installed: awk 1 /dev/null The [...] |
