loops - Assistance with bash code to extract data line by line -


i've been struggling new bash script i'm attempting write.

i have text file following contents:

/home/user1/public_html/pathtofile1 /home/user2/public_html/pathtofile2 /home/user3/public_html/packtofile3

i need code read text file line line, extract username can suspend , put full path (/home/user1/public_html/pathtofile1) reason getting suspended.

example of need automatically do:

/scripts/suspendacct user1 '/home/user1/public_html/pathtofile1' 1 /scripts/suspendacct user2 '/home/user1/public_html/pathtofile2' 1 /scripts/suspendacct user3 '/home/user1/public_html/pathtofile3' 1

i've tried "for loop" , "while read line" , i'm having 0 luck.

also needs exclude duplicate usernames.

any input appreciated. in advance.

your while loop approach fine, ran trouble parsing line. can use either parameter expansion/substring extraction or substring replacement parse needed information line. below example of parameter expansion/substring extraction:

#!/bin/bash  while read -r line;     usr="${line#/*/}"     usr="${usr%%/*}"     # /scripts/suspendacct $usr "'$line'"                   # uncomment use     printf "/scripts/suspendacct %s '%s'\n" $usr "$line"    # delete use done  exit 0

temporary output

$ bash suspendusr.sh <dat/usrpathtofile.txt /scripts/suspendacct user1 '/home/user1/public_html/pathtofile1' /scripts/suspendacct user2 '/home/user2/public_html/pathtofile2' /scripts/suspendacct user3 '/home/user3/public_html/packtofile3'

note: have printing /scripts/suspendacct call each user. have adjust script , uncomment actual call.

as have figured out, there half-dozen ways this. fine. choose approach comfortable with.

skip duplicates

declare -a uarray declare -i found=0  while read -r line;     usr="${line#/*/}"     usr="${usr%%/*}"     found=0     in "${uarray[@]}";         [ "$usr" = "$i" ] && found=1;     done     [ $found -eq 1 ] && continue     uarray+=( $usr )     # /scripts/suspendacct $usr "'$line'"                 # uncomment use     printf "/scripts/suspendacct %s '%s'\n" $usr "$line"  # delete use done

using individual check on each user better using name regex. prevent lesser included matches. (e.g. user11 , user111)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
