Return previous line with Findstr

I am running FINDSTR command to find specific text in .txt files. I want to print matching lines as well as 1 previous line.

findstr "ActualStartDate:"  * > a.txt

if my file is like this

abcd  
defg  
cds  
ActualStartDate: invalid date

Result should be like this

cds  
ActualStartDate: invalid date
Solution

  • try this with grep for Windows:

    grep -1 "ActualStartDate:" *.txt

    output is eg.:

    file.txt-cds
file.txt:ActualStartDate: invalid date
