Read from one file-Replace a pattern in another with the current one
Hi Friends, I have a text file like this Code:
cat main.txt I like this website cat website > new_website grep website > hello_website Code:
cat replace.txt hello unix apple Now, for each line read in 2.txt, I want the pattern "website" in 1.txt to be replaced with it. Basically, I will be getting wc number of files in 2.txt So, my final output files will be Code:
cat main1.txt I like this hello cat hello > new_hello grep hello > hello_hello Code:
cat main2.txt I like this unix cat unix > new_unix grep unix > hello_unix Code:
cat main3.txt I like this apple cat apple > new_apple grep apple > hello_apple I got an ide of the following, but I think I am missing something Code:
for i in `cat replace.txt`; do sed '/website/$i/s';done But, I am having trouble on listing the files and updating the file numbers. Thanks in advance. |

Try: Code:
awk 'NR==FNR{a[++n]=$0;next}{for (i=1;i<=n;i++){x=a[i];gsub ("website",$0,x);print x > "main"FNR".txt"}}' main.txt replace.txt |

Thanks for your time. This is the error I am seeing Code:
awk: syntax error at source line 1
context is
NR==FNR{a[++n]=$0;next}{for (i=1;i<=n;i++){x=a[i];gsub ("website",$0,x);print x > >>> "main"FNR <<< ".txt"}}
awk: illegal statement at source line 1---------- Post updated at 03:46 PM ---------- Previous update was at 03:45 PM ---------- Quote:
I neither see an error, nor my output files. Thanks for your time though. |

What operating system are you using? If Solaris then use nawk: Code:
nawk 'NR==FNR{a[++n]=$0;next}{for (i=1;i<=n;i++){x=a[i];gsub ("website",$0,x);print x > "main"FNR".txt"}}' main.txt replace.txt |

Slight modification to Bartus11's awk: Code:
awk '
NR==FNR{
a[++n]=$0
next
}
{
for (i=1;i<=n;i++){
x=a[i]
gsub ("website",$0,x)
f="main" FNR ".txt"
print x > f
}
}
' main.txt replace.txt |
